HP COLOR LASERJET ENTERPRISE M577F (01) PDF MANUAL

The DC controller PCA controls the operating sequence as follows:

Sleep mode conserves power after the printer has been idle for an adjustable period. The printer retains all settings, downloaded fonts, and macros in Sleep mode. The default setting is for Sleep mode to be enabled, and the printer enters Sleep mode after a 30-second idle time. In the General Settings menu (a submenu of the Administration menu), this item is termed Sleep Timer Settings.

The available states are, in descending order from using the most power to using the least power:

• Active: The printer control panel is fully illuminated. The power button light is illuminated.

• Shallow sleep: The printer control panel is dim and the content is grayed out, but is still readable. The power button light is illuminated.

• Sleep: The printer control panel is off (blacked out). The power button light blinks once every three seconds.

• Deep sleep: The printer control panel is off (blacked out). The power button light blinks once every three seconds. The control panel and power button appearance is the same in this state as the sleep state. However, the printer is drawing less than 1 watt of power in the deep sleep state (as opposed to 6 watts of power in the sleep state).

• Off: This state is entered by pressing the power button or removing power from the printer. The power button light is not illuminated.

Note: In some countries/regions, Sleep mode cannot be turned off.

The printer exits Sleep mode and enters the warm-up cycle when any of the following events occur:

• The printer receives a print job, valid data, or a PML or PJL command.

• A control-panel button is pressed or the touchscreen is touched.

• A cover or door is opened.

• The engine self-test switch is pressed.

• A paper tray, other than Tray 1, is opened.

Note: If the printer is in the deep sleep state, opening a paper tray will not cause the printer to exit Sleep mode.

Note: Printer error messages override the Sleep message. The printer enters Sleep mode at the appropriate time, but the error message continues to appear.

Tip: When the printer is in Sleep mode, the sub-power supply is off and the low-voltage power supply is on.

PJL is an integral part of printer configuration, in addition to the standard printer command language (PCL) and PostScript (PS). With standard cabling, the printer can use PJL to perform a variety of functions, such as these:

• Two-way communication with the host computer through a network connection or a USB device port: The printer can inform the host about the control-panel settings, and the control-panel settings can be changed from the host.

• Dynamic I/O switching: The printer uses this switching to be configured with a host on each I/O. The printer can receive data from more than one I/O simultaneously, until the I/O buffer is full. This can occur even when the printer is offline.

• Context-sensitive switching: The printer can automatically recognize the personality (PS or PCL) of each job and configure itself to serve that personality.

• Isolation of print environment settings from one print job to the next: For example, if a print job is sent to the printer in landscape mode, the subsequent print jobs print in landscape only if they are formatted for landscape printing.

This printer features easy-access USB printing for quickly printing files without sending them from a computer. The printer accepts standard USB flash drives in the USB port near the control panel. It supports the following types of files:

• .pdf

• .prn

• .pcl

• .ps

• .cht

The USB port is disabled by default. Follow the instructions in the printer user guide to enable the USB port and print USB documents.

The M553x and M577z models support NFC capabilities. NFC enables a connection between the printer and a mobile device, such as a smartphone or tablet, by touching the device to the NFC icon on the bottom of the control panel. Documents and images from the mobile device can then be printed through the wireless card on the printer.

If DC voltage is not being supplied from the low-voltage power supply, the protective function might be running. In this case, turn the power switch off and unplug the power cord.

Do not turn the power switch on until the root cause is found and corrected.

If the protective function is active, the DC controller notifies the formatter of a low-voltage power supply failure. In addition, the low-voltage power supply has two fuses to protect against over-current. If over-current flows into the AC line, the fuse stops the AC power.

Fuser heater protection is a feature that detects excessive temperatures in the fuser and interrupts the power supply to the fuser heater. The following three protective components prevent the fuser heater from excessive rising temperature:

• DC controller: When a thermistor or sub-thermistor detects a temperature above a certain threshold, the DC controller interrupts power to the specific heater.

• Fuser-heater safety circuit: The fuser heater safety circuit monitors the detected temperature of the sub-thermistors.

• Thermoswitch: If the temperature in the heaters is abnormally high, and the temperature in the thermoswitch exceeds a specified value, the contact to the thermoswitch breaks.

The fuser life is tracked by fuser rotations, and not by the number of pages printed. This is a more accurate tracking method since the fuser rotates for every print job. There will be variations in fuser life depending on customer usage. Customers who are running one- and two-page intermittent jobs with long pauses between each job might reach the fuser low message sooner due to the fuser rotating more times per page than it would for larger print jobs.

The printer detects the type and presence of the fuser. The DC controller notifies the formatter when it fails to detect the type or presence of the fuser.

Note: This printer detects if a fuser of the correct voltage for the printer is installed. If a fuser of the incorrect voltage is installed, the DC controller notifies the formatter and an error message is displayed on the control panel.

The image-formation process consists of ten steps divided into six functional blocks:

Step 1: Pre-exposure: Light from the pre-exposure LED strikes the surface of the photosensitive drum to remove any residual electrical charges from the drum surface.

Step 2: Primary charging: The primary-charging roller contacts the photosensitive drum and charges the drum with negative potential.

Step 3: Laser-beam exposure: The laser beam strikes the surface of the photosensitive drum in the areas where the image will form. The negative charge neutralizes in those areas, which are then ready to accept toner.

Step 4: Development: Toner acquires a negative charge as the developing cylinder contacts the developing blade. Because the negatively-charged surface of the photosensitive drums have been neutralized where they have been struck by the laser beam, the toner adheres to those areas on the drums. The latent image becomes visible on the surface of each drum.

Step 5: Primary transfer: The positively-charged primary-transfer rollers contact the ITB, giving the ITB a positive charge. The ITB attracts the negatively-charged toner from the surface of each photosensitive drum, and the complete toner image transfers onto the ITB.

Step 6: Secondary transfer: The paper acquires a positive charge from the secondary-transfer roller, and attracts the negatively-charged toner from the surface of the ITB. The complete toner image transfers onto the paper.

Step 7: Separation: The stiffness of the paper causes it to separate from the ITB as the ITB bends. The static-charge eliminator removes excess charge from the paper to make sure that the toner fuses correctly.

Step 8: Fusing: To create the permanent image, the paper passes through heated, pressurized rollers to melt the toner onto the page. Fusing bias is added to the pressure roller to improve the print quality.

Step 9: ITB cleaning: The cleaning blade scrapes the residual toner off the surface of the ITB. The residual toner feed screw deposits residual toner in the toner collection unit. The residual toner which cannot be removed by the cleaning blade is charged by the ITB cleaning brush, and then transferred from the ITB surface to the photosensitive drum by the primary transfer (T1) roller.

Step 10: Drum cleaning: The cleaning blade scrapes the residual toner off the surface of the photosensitive drum, and toner is deposited in the toner collection portion of the cartridge.

Toner level detection: The DC controller detects the remaining toner in the cartridge by the optical detection method and then notifies the formatter of the remaining toner level.

Cartridge life detection: Cartridge life detection is measured in two ways.

1. Toner level:

• For the first 75% of cartridge life, toner level is measured through pixel counting by the DC controller. Once the level reaches 25%, the toner level sensor utilizes electrical properties to determine the amount of toner remaining.

2. Rotations of internal components (OPC and developer roller):

• The DC controller monitors these two life parameters and reports them to the formatter as percent life remaining. End of cartridge life is determined by the lower value of the two.

CAT supports two features for managing toner cartridges:

• Authentication: The genuine HP authentication feature allows a customer to specify that only genuine HP supplies can be used in a printer. If a non-HP or used supply is installed, the printer will not print. This feature is disabled by default, and can be enabled or disabled from the control panel or the Embedded Web Server (EWS). If a genuine HP toner cartridge from another printer is moved to a printer with this feature enabled, the toner cartridge will authenticate and print, unless the toner cartridge has passed the low state. If the toner cartridge has passed the low state, an Unauthorized Cartridge message displays on the control panel. If a non-HP toner cartridge is used in a printer with this feature enabled, the message Unauthorized Cartridge appears on the control-panel display.

• Anti-theft: The toner cartridge anti-theft feature allows a customer to configure the printer to automatically lock genuine HP toner cartridges to a specific printer or fleet of printers when they are installed. A locked toner cartridge will only work in the specified printer or fleet of printers. This feature prevents toner cartridges from being stolen and used in another printer, or from being moved from an authorized printer to an unauthorized printer. This feature is disabled by default, and can be enabled or disabled from the control panel, the Embedded Web Server (EWS), or Web Jetadmin. When the anti-theft feature is enabled, the toner cartridge in a printer will only work in the specified printer or fleet of printers. If a locked toner cartridge is moved to another printer, the cartridge will not print and the message Protected Cartridge appears on the control-panel display. Note: When a toner cartridge is locked to a specific printer or fleet of printers, it cannot be unlocked. This is a permanent operation.

Depending on the requirements of the print job, the primary-transfer rollers engage with the ITB so it can receive toner from the photosensitive drums. The primary-transfer rollers have three engagement states:

The DC controller monitors several signals from the ITB unit to detect status.

ITB unit life detection: The DC controller detects whether the ITB unit is new by monitoring the new ITB unit sensor. The DC controller determines the ITB unit is at end of life and notifies the formatter when a specified number of pages are printed after the ITB unit is replaced. If swapping ITB units between two printers for troubleshooting purposes, be sure to return the ITB units to their original printers to maintain the correct life count.

Note: When installing a new ITB, refer to the instructions for resetting the ITB life counter in the installation guide provided with the replacement part.

ITB unit presence detection: The DC controller detects the presence of an ITB unit by monitoring the primary-transfer roller disengagement sensor. The DC controller turns on the primary-transfer disengagement solenoid for specified times during an initial rotation period when the following events occur:

• The printer is turned on

• The printer exits sleep mode

• The door is closed

The DC controller determines the absences of an ITB unit and notifies the formatter when it does not detect a specified signal from the new primary-transfer roller disengagement sensor.

The printer picks up one sheet of paper from Tray 1. Following are the sequence of steps for the Tray 1 pickup operation.

Note: Tray 1 and Tray 2 are optimal for paper pickup when using special paper or media other than 20 lb plain paper. For Tray 1, the printer increases the number of attempts to pick up a page, which increases the reliability of successfully picking the page from the tray and decreases the possibility of a mis-pick jam.

1. The pickup motor reverses when a print command is received from the formatter.

2. When the DC controller turns on the Tray 1 pickup solenoid, the Tray 1 pickup roller rotates and the lifting plate lifts.

3. As the lifting plate rises, the paper is picked up.

4. The Tray 1 separation pad removes any multiply-fed sheets, and one sheet is fed into the printer.

The Tray 1 media-out sensor (SR8) detects whether paper is present in Tray 1.

Tray 2 lift operation:

The printer keeps the paper stack surface at the correct pickup position. The Tray 2 lift-up operation is performed under the following conditions:

• The printer is turned on

• Tray 2 is installed

• The paper stack surface in Tray 2 lowers

The operational sequence of the Tray 2 lift operation is as follows:

1. The pickup motor (M5) rotates and the lifter moves up. Note that this printer uses the pickup motor rather than a dedicated lifter motor.

2. When the Tray 2 media stack surface sensor 2 detects the stack surface of media, the lifter motor stops.

3. The lifter motor rotates again to lift the lifter when the Tray 2 media stack surface sensor 1 detects the stack surface and then lowers during printing.

When a Tray 2 media stack surface sensors does not detect the stack surface within a specified time period after the lifter motor starts rotating, the DC controller determines a lifter motor failure and notifies the formatter.

Tray 2 paper pickup:

Following are the sequence of steps for the Tray 2 pickup operation.

Note: Tray 1 and Tray 2 are optimal for paper pickup when using special paper or media other than 20 lb plain paper. For Tray 1, the printer increases the number of attempts to pick up a page, which increases the reliability of successfully picking the page from the tray and decreases the possibility of a mis-pick jam.

1. The printer is turned on or Tray 2 is inserted.

2. The tray lift-up operation raises the lifting plate so paper can be picked up.

3. The pickup motor rotates when a print command is received from the formatter.

4. The Tray 2 pickup roller and Tray 2 feed roller rotate.

5. The Tray 2 pickup solenoid turns on at a specified time.

6. The Tray 2 pickup cam rotates.

7. As the pickup arm lowers, the Tray 2 pickup roller touches the surface of the paper stack.

8. One sheet of paper feeds into the printer.

The printer can straighten the paper without slowing the feed operation.

1. The leading edge of paper strikes the registration shutter, and the leading edge is aligned with the shutter.

2. As the feed rollers keep pushing the paper, the paper warps.

3. When the force is great enough, the registration shutter rotates, and the paper passes through straightened.

The DC controller adjusts the feed speed to improve the print quality depending on the paper type. The paper is fed at a specified speed according to the print mode designated by the formatter.

¹ Speed for both full color and black and white pages

1/1 speed = 210 mm/s

Pro speed = 174 mm/s

1/2 speed = 105 mm/s

1/3 speed = 70 mm/s

The duplexing unit reverses the paper and feeds it through the paper path to print the second side. The duplex reverse control reverses the paper after the first side is printed and feeds it to the duplex re-pickup position to print the second side of the page.

1. At a specified time after the first side of a page is printed, the duplex reverse motor rotates, and the duplex reverse solenoid is turned on.

2. The duplex flapper moves, and the paper feeds to the duplex reverse unit.

3. After a specified period of time, the duplex reverse motor reverses, and the paper feeds to the duplex feed unit.

4. The duplex reverse motor and the pickup motor move the paper to the duplex re-pickup position.

5. The duplex reverse motor and the duplex feed clutch stop, and the paper feed operation pauses.

6. After a specified period of time, the duplex reverse motor rotates, and the duplex feed clutch is turned on. The paper is then picked up again.

To prevent excessive wear on the pressure roller and help with jam-clearing procedures, the pressure roller pressurizes only during printing and standby. The DC controller reverses the fuser motor. The fuser motor rotates the fuser pressure-release cam.

The pressure roller depressurizes under the following conditions:

• The printer is turned off

• Any failure occurs

• During power-save mode

• A paper jam is detected

If the DC controller does not sense the fuser pressure-release sensor for a specified period after it reverses the fuser motor, it notifies the formatter that a fuser pressure-release mechanism failure has occurred.

Paper Pickup: The 550-sheet paper feeder picks up one sheet from the paper-feeder tray and feeds it to the printer.

Multiple Feed Prevention: The multiple-feed prevention for the 550-sheet paper feeder is operated in the same way as that of the printer base.

Tray Presence Detection: The presence detection for the 550-sheet paper feeder is the same way as that of the printer base.

Tray Lift Operation: The 550-sheet paper feeder keeps the paper stack surface at the correct pickup position. The tray lift operation occurs under the following conditions:

• The printer is turned on.

• The tray is inserted.

• The paper stack surface of the tray lowers.

The sequence occurs as follows:

1. The feeder tray-lifting motor rotates and the lifter moves up.

2. When the paper-feeder media-stack-surface sensor detects the stack surface of the paper, the lifting motor stops.

3. The lifting motor rotates again to lift the lifter when the paper-feeder media-stack-surface sensor detects the stack surface, and then lowers during printing.

If a tray media-stack-surface sensor does not detect a stack surface within a specified period after the lifting motor starts rotating, the paper feeder driver determines that the lifting motor has failed and notifies the formatter through the DC controller. The paper-feeder driver notifies the formatter if either of the paper-feeder media-stack-surface sensors fails to detect the stack surface within a specified period from when a lift-up operation starts.

Jam Detection: The 550-sheet paper feeder uses the feed sensor (SR21) and right door switch (SW20) to detect the presence of paper and to check whether paper has jammed. The 550-sheet paper feeder detects the following jams:

• Media input delay jam 1 (550-sheet paper feeder): Paper did not reach the registration sensor in time.

• Media input delay jam 2 (550-sheet paper feeder): Paper did not reach the source tray feed sensor in time.

• Media input delay jam 3 (550-sheet paper feeder): Paper did not reach the tray 3 feed sensor in time.

• Pickup stationary jam (550-sheet paper feeder): The feed sensor does not detect the trailing edge of paper within a specified time after the sensor detects the leading edge.

• Residual paper jam (550-sheet paper feeder): The feed sensor detects the presence of paper for a specified time during an automatic delivery operation.

• Right door open jam (550-sheet paper feeder): The right door open is detected during a paper feed operation.

The M577 printer supports single-pass electronic duplexing (e-duplex) copy jobs. Two separate scan modules scan the front-side and back-side of an e-duplex copy job page in a single pass through the document feeder. For the M577c/z models, the document feeder supports a smart background, which auto-crops and adjusts the image extents.

Sensors in the document feeder:

• ADF paper present sensor: Detects whether a document is present in the document feeder. If paper is present in the document feeder when copies are made, the printer scans the document using the document feeder. If no paper is present when copies are made, the printer scans the document using the scanner glass.

• ADF Y (length) sensor: Detects whether a legal-size original is present in the document feeder.

• ADF jam cover sensor: Detects whether the document feeder cover is open or closed.

• ADF paper path deskew sensor: Detects the top of the page as it enters the deskew rollers.

• ADF paper path pick success sensor: Detects a successful one page feed from the document feeder tray. Note: This sensor uses ultrasonic sound to detect a multi-page paper feed.

• Paper path sensor 1: Detects the top of the page as it approaches the front-side scan module (document feeder glass).

The document feeder also has a deskew operation and document feeder hinges.

Before you start troubleshooting, use this checklist to verify basic printer functions and to help isolate the problem.

1. Is the printer plugged into a working, grounded electrical outlet that meets the printer electrical specifications? Verify that the outlet is working by plugging in another electrical device. If the printer is plugged into a power strip, try plugging it directly into a wall outlet.

2. Is the printer power switch turned on?

3. Are all covers and doors closed?

4. Is print media correctly loaded in the input trays?

5. Are all interface cables correctly connected?

6. Is the printer Ready? If not, turn the printer off and then on again.

7. Print a Configuration Page. If the printer is connected to a network, an HP Jetdirect Configuration Page also prints.

8. If the Configuration Page does not print, check the control panel for error messages. If an error message appears, see the control panel message document (CPMD) or the event log messages section.

9. If the Configuration Page prints, check the following:

• Does the page print correctly? If not, troubleshoot the print-quality problem.

• Is the installed printer memory (RAM) and optional hard disk drive listed correctly on the Configuration Page? If not, turn the printer off, verify the installation of the DIMMs and optional hard disk drive, and then turn the printer on.

• Is the PCL, PCL XL, or PS printer language listed on the Configuration Page? If not, turn the printer off, verify the installation of the DIMMs, and then turn the printer on.

• If the printer is connected to a network, are the network settings correct? If not, verify the network configuration. Also verify that the network hardware (cables, hub, router, or switch) is correctly installed and working.

10. Test the printer from a computer. Send a print job from a software application. If the job does not print, try printing from a different software application or a different computer.

11. If the problem occurs only in specific situations, such as when using a certain software application, a certain printer driver, or a certain operating system, the problem might be specific to that situation.

For M552dn, M553n, M553dn models (4-line display):

1. Turn the printer off.

3. From the Administrator menu, select +A:Remote Admin.

4. From the Remote Admin menu, select 1:Start Telnet.

5. The message “Telnet server function initialized.” appears on the control-panel display. The Telnet connection will terminate when the printer reboots or the Telnet session is ended.

6. On the computer, open a command window. Click Start, type cmd in the search box, and then press Enter.

7. At the command prompt, type telnet <IP Address> (replace <IP Address> with the printer IP address), and then press Enter.

8. A PIN is required to connect to the printer. The PIN for the current Telnet session appears on the printer control-panel display. Type the PIN at the command prompt, and then press Enter.

9. The Remote Admin window appears on the computer display and the remote admin menu appears on the printer control-panel display. You can now control the printer from the command window on the computer.

1. In the Remote Admin window on the computer, type exit at the command prompt and press Enter, or click the X in the upper-right corner of the command window.

2. Press the Back button on the printer control panel to exit the Remote Admin menu.

Before escalating a problem, review this pre-troubleshooting checklist.

1. Check all external connections. Make sure that the power cord and interface cables are securely connected to the printer and to the computer or network port.

2. Check the printer power. Make sure that the printer power is on and that the printer is in the Ready state.

3. Check the printer control panel. Look for error messages that might indicate a specific problem.

4. Print a Configuration Page. If the printer is connected to a network, an HP Jetdirect Configuration Page also prints. Verify that the information on these pages is correct.

5. Check the print media. Make sure that the correct type of print media is loaded in the input trays and that the print media is not wrinkled, damaged, or too old.

6. Check the printer driver settings. Make sure that the printer driver settings are correct for the print job.

7. Try printing from a different software program. If the problem occurs only with a specific software program, the problem is probably with that program.

8. Try printing to a different printer. If the problem occurs with all printers, the problem is probably with the computer or the software program.

9. If the printer is connected to a network, try printing from a different computer on the network. If the problem occurs only with a specific computer, the problem is probably with that computer or its network connection.

Following is the basic sequence of operation for a document feeder simplex job.

1. The ADF jam cover sensor detects when the cover door is in the closed position.

2. The ADF paper present sensor activates when paper is loaded onto the input tray.

3. The feed motor rotates to raise the lift plate and starts to pick the loaded paper.

4. The ADF multi-pick (ultrasonic) sensor activates when the leading edge of the media is driven past the sensor. The printer firmware registers a successful pick operation.

5. The ADF paper path deskew activates when the leading edge of the paper passes it. The printer firmware registers the leading edge of the paper position.

6. The leading edge of the paper drives into the nip point of the deskew drive roller and the deskew pinch rollers. This creates a buckle of paper by the nip point for pick-skew correction.

7. The deskew motor rotates the deskew drive roller to pull the paper into the prescan drive roller.

8. The pick motor stops turning and allows both the pick and feed roller to turn freely while the paper is pulled in by the deskew drive roller.

9. The feed motor rotates to drive the paper into the prescan front-side sensor. The firmware registers the leading edge position of the paper as the multi-pick sensor activates.

10. The feed motor continues to rotate and drive the leading edge of the paper through the preset distance from the multi-pick sensor to the front-side scan zone. The scanner begins the scanning and data retrieval process.

11. The ADF multi-pick (ultrasonic) sensor deactivates when the trailing edge of the paper passes the sensor. The firmware registers the trailing edge of the paper position.

12. The feed motor continues to rotate and drive the trailing edge of the paper through the preset distance from the ADF multi-pick (ultrasonic) sensor to the front-side scan zone. The scanner ends the scanning and data retrieval process.

13. The feed motor continues to rotate and ejects the trailing edge of the paper into the output bin.

14. One of the following occurs:

• If the copy job is complete, the ADF paper present sensor deactivates. The feed motor reverses rotation to raise the pick roller.

• If the copy job is not complete, the ADF paper present sensor is active. The printer firmware detects additional pages in the input tray and the process repeats.

Following is the basic sequence of operation for a document feeder simplex job.

NOTE: For an e-duplex copy job, the background scan operation begins immediately after the simplex sequence of operation ends.

1. The feed motor continues to drive the paper until the leading edge activates the prescan back-side sensor. The printer firmware registers the position of the leading edge of the paper.

2. The feed motor continues to rotate to drive the leading edge of the paper through the preset distance from prescan back-side sensor to the back-side background selector scan zone. The back-side background scan module begins scanning and retrieval of the data.

3. The prescan back-side sensor deactivates when the trailing edge of the paper passes it. The printer firmware registers the trailing edge of the paper position.

4. The feed motor continues to rotate to drive the trailing edge of the paper edge past the back-side background selector scan zone.

5. The feed motor continues to rotate and ejects the trailing edge of the paper into the output bin.

6. One of the following occurs:

• If the copy job is complete, the ADF paper present sensor deactivates. The feed motor reverses rotation to raise the pick roller.

• If the copy job is not complete, the ADF paper present sensor is active. The printer firmware detects additional pages in the input tray and the process repeats.

Sliding side guides on the input tray make sure that the paper stack is correctly aligned at the center of the input tray when paper is loaded in the tray. The correct position of the loaded paper is parallel with the direction of travel into the document feeder paper path.

The document feeder further reduces paper skew due to improper loading of paper in the input tray by buckling the paper to create a paper buffer.

The document feeder aligns the leading edge of the paper parallel with the deskew drive rollers before it is driven further into the document feeder paper path.

The document feeder hinges allow positioning the assembly vertically above the scanner glass to accommodate the placement of books and other objects up to 25 mm (1.0 in) in height on the scanner glass. The document feeder still closes (the bottom of the document feeder is kept parallel to the scanner glass) and allows the printer to operate.

The document feeder hinges provide height adjustment of 25 mm (1.0 in) when a maximum downward force of 4.5 kg (10 lb) is applied at the front edge of the assembly, with the fulcrum (such as the spine of a book) centered on the scanner glass and parallel to its long axis.

The document feeder will withstand a downward force of at least 4.5 kg (10 lb) applied at the front edge center of the assembly—when the fulcrum (such as the spine of a book) is located anywhere on the scanner glass and parallel to its long axis—without breaking, deforming, detaching or experiencing performance degradation.

The document feeder hinges support the assembly in the open position and prevent the document feeder from suddenly closing in a damaging or loud manner.

The hinges can hold the document feeder static in all positions higher than 100 mm (3.93 in); measured at the front of the assembly. Less than 2.3 kg (5 lb) of force is required to open or close the document feeder.

The hinges allow the document feeder to open to an angle of between 60º and 80º from the horizontal position (this angle will not allow the printer to tip over).

If the control panel is blank or black, check the following before proceeding:

• Check the power cable.

• Check that the power is turned on.

• Make sure that the line voltage is correct for the printer power configuration. (See the label that is on the back of the printer for voltage requirements.) If a power strip is in use, and its voltage is not within specifications, connect the printer directly into the electrical outlet. If it is already connected into the outlet, try a different outlet.

If the control panel is not responding to touch (M553x or M577 models), or if it appears black or blank, follow the steps below.

NOTE: The following conditions indicate that the printer has frozen while in Sleep mode:

• The control-panel home button LED is illuminated.

• The power-switch LED flashes once every three to five seconds.

Opening a door, tapping the control panel (M553x and M577 models), or pressing a control-panel button (M552dn and M553n/dn models) causes the printer to wake up from Sleep mode.

a. Turn the printer power off, and then on again.

b. Try upgrading the firmware. If the firmware upgrade fails to resolve the problem, elevate the case after collecting the following information:

• Try printing to the printer from a host computer. Does the printer print a page?

• Is the printer HP Embedded Web Server (EWS) accessible?

• Turn the printer power off, and then on again. Save the printer diagnostic file.

1. From the Home screen on the printer control panel, scroll to and touch the Administration option.

2. Scroll to and touch the Troubleshooting option.

3. Scroll to and touch the Generate Debug Data option, and then touch the Start button. Wait for the operation to complete.

The Remote Admin feature allows remote access to the printer Pre-boot menu (BIOS environment). The printer functions as a telnet server, which uses the telnet networking protocol to transmit text data. Any computer (with telnet installed and enabled) can function as the telnet client to remotely display and interact with the Pre-boot menu.

IMPORTANT: While the Remote Admin function allows remote access to the Pre-boot menu, for security reasons, the Remote Admin connection must be initiated by a person that is physically present at the printer.

This section describes the following Remote Admin items:

• Required software and network connection

• Connect a remote connection

• Disconnect a remote connection

Required software and network connection:

Before using the Remote Admin feature, make sure that the telnet network protocol is installed, and enabled, on the remote telnet client computer.

NOTE: This section describes enabling and configuring the telnet feature for computers using a Windows® operating system.

HP recommends that the telnet client computer be a Windows-based system, however, there are other operating systems that support the telnet network protocol. For information about enabling and configuring the telnet network protocol for other operating systems, see the owner’s manual for that operating system.

All computers using the Windows operating system have the telnet client installed, however, the telnet client function might not be enabled by default.

NOTE: The figures and menus in this section are for the Windows 7 Enterprise® operating system. Screens and menu selections might vary slightly for other operating systems.

1. Use the Start menu to open the Control Panel, and then click the Programs item to select it.

2. Click the Turn Windows features on or off item to select it.

3. In the Windows Features box, scroll down to Telnet Client. If the check box is not checked, click the box to select it, and then click the OK button.

TIP: If the check box is already checked then the telnet client function is already enabled. Click the Cancel button.

The remote telnet client computer must have direct network access to the printer for the Remote Admin function to operate. This means that the telnet client computer must be on the same network as the printer. The Remote Admin function cannot be accessed through a network firewall or other remote access network security programs.

If a private network is not accessible, ask the network administrator to set up a virtual private network (VPN) connection to the network.

For security reasons the Remote Admin feature must be initiated by a person that is physically present at the printer. The following steps must be performed by a person that is physically present at the printer.

NOTE: This person might need to sign in with an administrator or service password depending on how the printer is configured.

1. Turn the printer on.

2. The HP logo displays on the printer control panel. When a 1/8 displays below the logo, touch in the middle of the control-panel display to open the Pre-boot menu.

3. Use the arrow buttons on the touchscreen to scroll down and highlight the +3:Administrator item, and then touch the OK button to select it.

4. Use the arrow buttons on the touchscreen to scroll down and highlight the +A:Remote Admin item, and then touch the OK button to select it.

5. Use the arrow buttons on the touchscreen to scroll down and highlight the 1:Start Telnet item, and then touch the OK button to select it.

6. Do one of the following:

• If a connecting message displays briefly, go to step 7.

• If an error message displays, use the steps below to identify the problem.

If a “Start Telnet Unable to connect Contact network administrator.” message appears:

a. The printer network cable is not correctly connected BIOS LAN settings are incorrect.

• The printer should be configured to use a static IP address, but is configured to use DHCP instead.

• The printer is configured to use a static IP address, but the IP address is incorrect.

b. The printer is correctly configured to use DHCP, but the DHCP server is not turned on or is malfunctioning.

When the printer telnet server function is initialized, the following screen appears. Use the information on this screen to connect the remote telnet client computer to the printer.

NOTE: The printer is now ready to receive remote telnet client commands.

• IP: The static or dynamically allocated IP address for the printer.

• Port: The standard telnet port (23).

• Pin: A randomly generated 4-digit personal identification number (PIN).

Example: Start Telnet, IP: 16.88.109.66, Port: 23, Pin: 4031

The following steps establish a Remote Admin connection from a remote computer to the printer.

1. From the Start menu click Run to open a dialog box, type cmd in the Open field, and then click the OK button to open a Windows command window.

2. From any displayed directory, type telnet at the prompt, and then press the Enter key.

3. Type o <IP ADDRESS> at the telnet prompt, and then press the Enter key.

NOTE: For <IP ADDRESS>, substitute the IP address that was displayed in step 7 in Start the telnet server function at the printer.

TIP: If the telnet connection fails to establish a connection, the printer is probably behind a firewall or on a different network that the remote telnet client computer. See Network connection.

4. Type the PIN that was displayed in step 7 in Start the telnet server function at the printer at the prompt, and then press the Enter key.

IMPORTANT: Make sure to type the PIN correctly. After five incorrect PIN entries, the printer terminates the Remote Admin connection. The Remote Admin feature must be re-initiated at the printer.

5. The Remote Admin screen displays when the correct PIN is entered and the Remote Admin connection is successful. For information about the Pre-boot menu and options, see Pre-boot menu options.

NOTE: Because a Remote Admin connection is an unsecure telnet network protocol connection, the following Pre-boot menu items are disabled for the remote telnet client computer.

• The +3:Administrator menu 4:Change Password item.

• The +3:Administrator menu 5:Clear Password item.

• The +3:Administrator menu 6:Disk Manage item.

The Remote Admin connection can be terminated from the printer control panel or the remote telnet client computer.

NOTE: The following procedure describes terminating a Remote Admin connection from the remote telnet client computer.

1. From the Pre-boot main menu (displayed on the remote telnet client), use the arrow buttons on the keyboard to scroll down to the +3:Administrator item, and then press the Enter key.

2. Use the arrow buttons on the keyboard to scroll down to the +A:Remote Admin item, and then press the Enter key.

3. Use the arrow buttons on the keyboard to scroll down to the 2:Stop Telnet item, and then press the Enter key. The Remote Admin connection between the printer and the remote telnet client computer terminates.

IMPORTANT: The printer remains in the Pre-boot menu. Have the person that is physically present at the printer do the following:

• Touch the Home button to return to the main Pre-boot menu and highlight the 1:Continue item, and then touch the OK button. The printer will continue to initialize.

When the printer malfunctions or encounters an unexpected situation, the printer control panel alerts the user to the situation. This section contains a pre-troubleshooting checklist and a troubleshooting flow chart to filter out many possible causes of the problem. Use the pre-troubleshooting checklist to gather information about the problem from the customer. Use the troubleshooting flowchart to help diagnose the root cause of the problem. The remainder of this chapter provides steps for correcting problems.

• Use the pre-troubleshooting check list to gather information about the problem from the customer.

• Use the troubleshooting flowchart to pinpoint the root cause of hardware malfunctions. The flowchart provides guides to the section of this chapter that contain steps to correct the malfunction.

Before beginning any troubleshooting procedure, check the following issues:

• Are supply items within their rated life?

• Does the configuration page reveal any configuration errors?

NOTE: The customer is responsible for checking supplies and for using supplies that are in good condition.

This flowchart highlights the general processes to follow to quickly isolate and solve printer hardware problems.

Each row depicts a major troubleshooting step. Follow a “yes” answer to a question to proceed to the next major step. A “no” answer indicates that more testing is needed. Go to the appropriate section in this chapter, and follow the instructions there. After completing the instructions, go to the next major step in this troubleshooting flowchart.

The basic printer functions should start up when the printer is connected into an electrical outlet and the power switch is pushed to the on position. If the printer does not start, use the information in this section to isolate and solve the problem.

If the control panel display remains blank, random patterns display, or asterisks remain on the control panel display, perform power-on checks to find the cause of the problem.

During normal operation, a cooling fan begins to spin briefly after the printer power is turned on. Place a hand over the vents in the rear cover, near the formatter. When the fan is correctly operating, air passing out of the printer is felt. Lean close to the printer to hear the fan operating. If the fan is operating, the dc side of the power supply is functioning.

After the fan is operating, the main motor turns on (unless the top cover is open, a jam condition is sensed, or the paper-path sensors are damaged). Visually and audibly determine that the main motor is turned on.

If the fan and main motor are operating correctly, the next troubleshooting step is to isolate printer, formatter, and control panel problems. Perform an engine test. If the formatter is damaged, it might interfere with the engine test. If the engine-test page does not print, try removing the formatter, and then performing the engine test again. If the engine test is then successful, the problem is almost certainly with the formatter, the control panel, or the cable that connects them.

1. Verify that power is available to the printer. If the printer is plugged into a surge protector or uninterruptible power supply (UPS), remove it, and then plug the printer directly into a known operating wall receptacle (make sure that the wall receptacle provides the correct voltage and current for the printer).

Unplug any other devices on the same circuit that the printer is using.

2. Try another known operating wall receptacle and a different power cord.

3. Listen for startup noises (fans and motors) and illuminated lights on the control panel.

NOTE: Operational fans, motors, and control-panel lights indicate the following:

• AC power is present at the printer.

• The low-voltage power supply (LVPS) is providing either or both 24 Vdc and 5 Vdc voltages.

• The DC controller microprocessor is functioning.

4. Check the following:

a. Turn the printer on, and then listen for startup noises. If normal startup noises are heard, go to step c below.

b. If normal startup noises are not heard, turn the printer off, and then remove any installed accessories (for example, paper feeders).

Turn the printer on, and then listen for startup noises. If normal startup noises are heard, the problem might be with one of the accessories.

c. Turn the printer off and then remove the power connector from the formatter. Turn the printer on, and then use a small pointed object (like a paper clip) to depress the test-page switch located on the rear side of the printer (near the formatter).

NOTE: The test page can only use Tray 2 as the paper source, so make sure that paper is loaded in Tray 2.

d. If the engine test page prints, the print engine is operating normally.

e. If the engine test page does not print, replace the low-voltage power supply (LVPS):

• RM2-7165-000CN (M552, M553)

• RM2-7164-000CN (M577)

f. If, after replacing the LVPS, normal startup noises are still not heard, replace the DC controller:

• RM2-7186-000CN (M552, M553)

• RM2-7187-000CN (M577)

g. If after replacing the DC controller normal startup noises are still not heard, replace the fuser power supply (RM2-7125-000CN).

NOTE: If the error persists after replacing these assemblies, escalate the problem to the Global Business Unit (GBU).

A blank control panel display can be caused by one or more of the following:

• No power to the printer

• Power supply has tripped (over-current/over-voltage/temperature issue)

• Connectors on the formatter are not fully seated

TIP: The three LEDs on the formatter indicate that the printer is functioning correctly.

HP recommends fully troubleshooting the formatter and control panel before replacing either assembly. Use the connectivity LED to troubleshoot formatter and control panel errors to avoid unnecessarily replacing these assemblies. See the LED diagnostics section in the printer troubleshooting manual.

• Faulty component installed on the formatter (for example, memory DIMM or disk drive)

• Control panel connectors not fully seated

• Faulty formatter

• Faulty control panel

1. Verify that power is available to the printer. If the printer is plugged into a surge protector or uninterruptible power supply (UPS), remove it, and then plug the printer directly into a known operating wall receptacle (make sure that the wall receptacle provides the correct voltage and current for the printer).

2. Make sure that the power switch is in the on position.

3. Make sure that the fan runs briefly, which indicates that the power supply is operational.

4. Make sure that the control-panel display wire harness is connected.

5. Make sure that the formatter connectors are seated. Make sure the power switch is in the on position, and then verify that the heartbeat LED is blinking and that the connectivity LED is illuminated.

6. Remove any external solutions, and then try to turn the printer on again.

7. If the control panel display is blank, but the main cooling fan runs briefly after the printer power is turned on, try printing an engine-test page to determine whether the problem is with the control-panel display, formatter, or other printer assemblies.

a. Disconnect all of the formatter connectors.

b. Use a small pointed object to depress the test-page switch located on the rear of the printer.

NOTE: The test page can only use Tray 2 as the paper source, so make sure that paper is loaded in Tray 2.

c. If the engine test page prints, the print engine is operating normally (a failed engine test print page does not necessarily indicate that the print engine or DC controller is defective).

d. Use the control-panel diagnostics to test the control panel. See the Control panel checks section in the printer troubleshooting manual. If the error persists, proceed to step 8.

8. If the print engine appears to be correctly operating (the engine test page successfully printed) and the control panel is still blank, replace the low-voltage power supply (LVPS).

9. If after replacing the LVPS normal startup noises and lights are still not present, replace the DC controller.

NOTE: If the error persists after replacing these assemblies, escalate the problem to the Global Business Unit (GBU).

NOTE: The printer includes a diagnostic test mode for the touchscreen control panel. Diagnostic tests are not available for the LCD control panel.

Two LEDs on the formatter indicate that the printer is functioning correctly.

1. Heartbeat LED

2. HP Jetdirect LEDs

Heartbeat LED:

The heartbeat LED indicates that the formatter is functioning correctly. While the product is initializing after it is turned on, the LED blinks rapidly, and then turns off. When the product has finished the initialization sequence, the heartbeat LED pulses on and off.

The following table describes the heartbeat LED operation while the product is executing the firmware boot process.

NOTE: When the initialization process completes, the heartbeat LED should be illuminated solid green. If after initialization, the heartbeat LED is not solid green, see Table 2-10 Heartbeat LED, product operational.

The embedded HP Jetdirect print server has two LEDs. The yellow LED indicates network activity, and the green LED indicates the link status. A blinking yellow LED indicates network traffic. If the green LED is off, a link has failed.

For link failures, check all the network cable connections. In addition, try to manually configure the link settings on the embedded print server by using the printer control-panel menus.

1. From the Home screen on the printer control panel, scroll to and touch the Administration button.

The printer contains extensive internal engine diagnostics that help in troubleshooting print quality, paper path, noise, assembly, and timing issues.

To verify that the printer engine is functioning, print an engine test page. Use a small pointed object to depress the test-page switch located on the rear of the printer. The test page should have a series of lines that are parallel to the short end of the page. The test page can use only Tray 2 as the paper source, so make sure that paper is loaded in Tray 2.

Different tests can be used to isolate different types of issues. For assembly or noise isolation, run the diagnostic test when the front door or right door is open. To operate the printer with the doors open, the interlock switch levers must be depressed to simulate a closed-cover position.

WARNING! Be careful when performing printer diagnostics to avoid risk of injury. Only trained service personnel should open and run the diagnostics with the covers removed. Never touch any of the power supplies when the printer is turned on.

TIP: Fold a stiff piece of paper, for example a business card or index card, into a 10 mm (.375 in) strip, and insert the strip into the slots for the front door and right door logic switches.

1. Open the front door, and then insert a folded piece of paper into one slot.

2. Open the right door, and then insert a folded piece of paper into two slots (one on the right side, one on the left side).

Description

A job framework internal error has occurred.

Recommended action

1. No action should be necessary.

2. If the error persists, upgrade the product firmware.

3. If the issue persists, continue troubleshooting with the flowcharts for either Intermittent or Persistent 49 error troubleshooting (whichever is appropriate) in document c03122817, “HP LaserJet FutureSmart Devices – 49 Error Troubleshooting (Persistent and Intermittent)”.

Description

A firmware error occurred. Corrupted print jobs, software application issues, non-product specific print drivers, poor quality USB or network cables, bad network connections or incorrect configurations, invalid firmware operations, or unsupported accessories can cause this error.

Recommended action

1. Turn the product off, and then on.

2. If the error persists, check the following:

• The error might be caused by a network connectivity problem, such as a bad interface cable, a bad USB port, or an invalid network configuration setting.

• The error might be caused by the print job, due to an invalid print driver, a problem with the software application, or a problem with the file being printed.

• Upgrading the product firmware might help resolve the error. See the product user guide for more information.

When a 49 error occurs, the user sees a 49.XXXX message on the control panel (where XXXX is replaced by a combination of letters and numbers). A 49 error might happen at any time for multiple reasons. Although some types of 49 errors can be caused by hardware failures, it is more common for 49 errors to be caused by printing a specific document or performing some task on the product.

49 errors most often occur when a product is asked to perform an action that the product firmware is not capable of and might not have been designed to comply with, such as:

• Printing files with unsupported programming commands

• A unique combination of user environment and user interactions with the product

• Interfacing with a third-party solution that was not designed to work with the product

• Specific timing, network traffic, or concurrent processing of jobs

Each of these interactions could cause the product firmware to initiate an action that the product cannot accomplish. In situations like this, the product might present the error if it has no other option. When these errors occur, the only way to recover is to turn the product’s power off and back on.

NOTE: LaserJet formatter PCAs are rarely the root cause of 49 service errors. Please do not replace the formatter or flash unless troubleshooting has identified the formatter as the root cause.

If the error persists, continue troubleshooting with the flowcharts for either Intermittent or Persistent 49 error troubleshooting (whichever is appropriate) in document c03122817, “HP LaserJet FutureSmart Devices – 49 Error Troubleshooting (Persistent and Intermittent)”.

Print speed is the number of pages that print in one minute. Print speed depends on different engine-process speeds or operational pauses between printed pages during normal printer operation. Factors that determine the print speed of the printer include the following:

Page formatting time

The printer must pause for each page to be formatted before it prints. Complex pages take more time to format, resulting in reduced print speed. However, most jobs print at full engine speed.

Media size

Legal-size media reduces print speed because it is longer than the standard Letter- or A4-size media. A reduced print speed is used when printing on narrow media to prevent the edges of the fuser from overheating.

Media mode

Some media types require a reduced print speed to achieve maximum print quality on that media. For example, glossy, heavy, and specialty media (for example, envelopes or photos) require a reduced print speed. To maximize the print speed for special media types, make sure that the correct media type in the print driver is selected.

Printer temperature

To prevent printer damage, print speed is reduced if the printer reaches a specific internal temperature (thermal slow down). The starting temperature of the printer, ambient environment temperature, and the print job size effect the number of pages that can be printed before the printer reduces the print speed. Thermal slow down reduces print speed by printing four pages and then pausing for an amount of time before printing continues.

Other print speed reduction factors

Other factors (especially during large print jobs) that can cause reduced print speeds include:

Density control sequence; occurs every 150 pages and takes about 120 seconds

If the printer does not print at all, try the following solutions.

1. Make sure the printer is turned on and that the control panel indicates it is ready.

If the control panel does not indicate the printer is ready, turn the printer off and then on again.

If the control panel indicates the printer is ready, try sending the job again.

2. If the control panel indicates the printer has an error, resolve the error and then try sending the job again.

3. Make sure the cables are all connected correctly. If the printer is connected to a network, check the following items:

Check the bottom LED next to the network connection on the printer. If the network is active, the light is green.

Make sure that a network cable and not a phone cord is used to connect to the network.

Make sure the network router, hub, or switch is turned on and that it is working correctly.

4. Install the HP software from the CD that came with the printer. Using generic printer drivers can cause delays clearing jobs from the print queue.

5. From the list of printers on your computer, right-click the name of this printer, click Properties, and open the Ports tab.

If a network cable is used to connect to the network, make sure the printer name listed on the Ports tab matches the printer name on the printer configuration page.

If a USB cable is used, and the printer is connected to a wireless network, make sure the box is checked next to Virtual printer port for USB.

6. If a personal firewall system on the computer is used, it might be blocking communication with the printer. Try temporarily disabling the firewall to see if it is the source of the problem.

7. If the host computer or the printer is connected to a wireless network, low signal quality or interference might be delaying print jobs.

If the printer prints, but it seems slow, try the following solutions.

1. Make sure the computer meets the minimum specifications for this printer.

2. When the printer is configured to print on some paper types, such as heavy paper, the printer prints more slowly so it can correctly fuse the toner to the paper. If the paper type setting is not correct for the type of paper you are using, change the setting to the correct paper type.

3. If the host computer or the printer is connected to a wireless network, low signal quality or interference might be delaying print jobs.

When replacing the formatter, the date is lost. Use this menu item to reset the date to the original date that the printer was first used. The date format is YYDDD. Use the following formula to calculate the dates:

1. To calculate YY, subtract 1990 from the calendar year. For instance, if the printer was first used in 2002, calculate YY as follows: 2002 – 1990 = 12. YY = 12.

2. Subtract 1 from 10 (October is the tenth month of the year): 10 – 1 = 9.

Multiply 9 by 30: 9 x 30 = 270 or add 17 to 270: 270 + 17 = 287. Thus, DDD = 287.

Use the printer Service ID number to determine whether the printer is still under warranty. Use the following formula to convert the Service ID into the installation date as follows:

1. Add 1990 to YY to get the actual year that the printer was installed.

2. Divide DDD by 30. If there is a remainder, add 1 to the result. This is the month.

3. The remainder from the calculation in step 2 is the date.

Using the Service ID 12287 as an example, the date conversion is as follows:

1. 12 + 1990 = 2002, so the year is 2002.

2. 287 divided by 30 = 9 with a remainder of 17. Because there is a remainder, add 1 to 9 to get 10, which represents October.

3. The remainder in step 2 is 17, so that is the date.

4. The complete date is 17-October-2002.

NOTE: A six-day grace period is built into the date system.

Active and repository firmware locations

The firmware bundle consists of multiple parts. The main components are the Windows CE Operating System and the printer/peripheral firmware files.

There are two locations/partitions on the hard drive where the firmware components are stored:

The Active, where the operating system and firmware currently are executing.

The Repository, the recovery location.

If the Active location is damaged, or a Partial Clean was performed, the printer automatically copies over the OS and firmware files from the Repository location and the printer recovers.

If both the Active and Repository locations are damaged, or a Format Disk was performed, then both locations are gone and the error message 99.09.67 displays on the control-panel display. The user must upload the firmware to the printer in order for it to function again.

CAUTION: The Format Disk option performs a disk initialization for the entire disk. The operating system, firmware files, and third party files (among other files) will be completely lost. HP does not recommend this action.

Partial Clean

The Partial Clean option erases all data from the partitions, except for the firmware repository where a backup copy of the firmware file is stored. This allows the disk drive to be reformatted without having to download a firmware upgrade file to return the printer to a bootable state.

Characteristics of a Partial Clean

Customer-defined settings, third-party solutions, firmware files, and the operating system are deleted.

Rebooting the printer restores the firmware files from the Repository location, but does not restore any customer-defined settings.

For previous HP products, a Hard Disk Initialization is similar to executing the Partial Clean function for this printer.

CAUTION: HP recommends backing-up printer configuration data before executing a Partial Clean to retain customer-defined settings (if needed). See the Backup/Restore item in the Device Maintenance menu.

Reasons for performing Partial Clean

4. If the switches do not respond, replace the associated lifter drive assembly.

Tray 2 — RM2-0010–000CN

External 550 Sheet feeder — RM2-5149–000CN

The tray is filled above the stack-height mark.

X = 2: Tray 2

X = 3: Tray 3

X = 4: Tray 4

X = 5: Tray 5

The overfilled condition is sensed by the stack surface sensor when the tray is first closed. If the stack surface sensor does not move down (because the tray is too full), the overfilled message will be displayed and the tray will not be available for printing.

Recommended action:

1. Open the tray and remove paper until the tray filled indicators can be seen.

2. Close the tray.

3. If the issue persists after removing paper from the tray, replace Paper Pickup Assembly.

NOTE: Before replacing the Paper Pickup Assembly perform the following steps.

a. Perform a tray bin sensor test for the paper stack sensor of the tray in question.

(Example) Perform a manual sensor test for SR12 tray 2 paper surface sensor.

This test requires the activation of the tray closed lever which releases the sensor arms for the paper surface sensors.

b. Verify that all connections from the DC Controller to the Paper pickup assembly and Lifting drive assembly are fully seated and connected. A loose or missing connection can cause this error.

c. If this message appears after lifter drive assembly was removed or replaced, make sure that the connector on the assembly is correctly connected and fully seated.

d. If the error persists, replace the paper pickup assembly.

When troubleshooting the source of some print image defects, one solution is to identify if it is a repetitive defect (does the print quality defect appear multiple times on the printed page?). If this is the case, use a ruler to measure occurrences of repetitive image defects to help solve image-quality problems.

Place the ruler next to the first occurrence of the defect on the page. Find the distance between identical defects and use the table below to identify the component that is causing the defect.

IMPORTANT: Do not use solvents or oils to clean rollers. Instead, rub the roller with lint-free paper. If dirt is difficult to remove, rub the roller with lint-free paper that has been dampened with water.

NOTE: Defects on the tray pickup rollers or the Tray 1 pickup roller do not cause a repetitive defect. Defects on these rollers cause a defect to appear only on the leading edge of the image.

TIP: To make a printer specific repetitive defect ruler, use a metric ruler to transfer the measurements in the table below to a transparency or the edge of a piece of paper—clearly label each ruler mark with the associated defective assembly.

¹ The primary charging roller, photosensitive drum and developer roller cannot be cleaned. If any of these rollers are indicated, replace the toner cartridge.

² The primary fuser sleeve unit or pressure roller cannot be cleaned because they are internal assemblies in the fuser. If one of these assemblies is causing the defect, replace the fuser.

Steps to measure:

1. Identify a repetitive defect on the page.

TIP: Print a cleaning page to see if that resolves the defect.

2. Position a metric ruler on the page with the “zero” ruler mark at one occurrence of the defect.

3. Locate the next occurrence of the defect.

4. Measure the distance (in millimeters) between the two occurrences, and then use Table 2-51 to determine the defective assembly.

TIP: Always measure from and to the same point on the defects. For example, if the ruler is “zeroed” at the top edge of a defect, measure to the top edge of the next occurrence of that defect.

Step one: Use paper that meets HP specifications

Always use a paper type and weight that this printer supports.

Use paper that is of good quality and free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, voids, staples, and curled or bent edges.

Use paper that has not been previously printed on.

Use paper that does not contain metallic material, such as glitter.

Use paper that is designed for use in laser printers. Do not use paper that is designed only for use in Inkjet printers.

Use paper that is not too rough. Using smoother paper generally results in better print quality

Step two: Check the environment

The environment can directly affect print quality and is a common cause for print-quality or paper-feeding issues. Try the following solutions:

Move the printer away from drafty locations, such as open windows or doors, or air-conditioning vents.

Make sure the printer is not exposed to temperatures or humidity outside of printer specifications.

Do not place the printer in a confined space, such as a cabinet.

Place the printer on a sturdy, level surface.

Remove anything that is blocking the vents on the printer. The printer requires good air flow on all sides, including the top.

Protect the printer from airborne debris, dust, steam, grease, or other elements that can leave residue inside the printer.

Try the following manual print modes to see if they solve the image-quality problems.

NOTE: Tray 1 and Tray 2 are optimal for paper pickup when using special paper or media other than 20lb plain paper. For Tray 1 and Tray 2 the printer increases the number of attempts to pick up a page, which increases the reliability of successfully picking the page from the tray and decreases the possibility of a mispick jam.

HP recommends using Tray 1 or Tray 2 if the printer is experiencing excessive or reoccurring jams from trays other than Tray 1 and Tray 2, or for print jobs that require media other than 20lb plain paper.
