HP LaserJet Service PIN Codes

An HP Laserjet Service area PIN being entered into an HP printer being serviced

The Laserjet Service Menu is used by printer repair engineers and usually has options like clearing the event log, changing the maintenance count and maintenance interval.
Most HP laserjet printer models require a PIN code to access the Service Menu Area. PIN codes for each model can be found in the individual laserjet service manuals, however here is a useful list for quick reference.
If you are not a qualified laser printer engineer, please be careful in this area as you are able to overwrite important and critical data.
Our engineers often refer to this table when refurbishing printers to ensure that the page counts for the fuser and transfer kits are correct and to help the printer to default to the correct paper size following a cold reset (Power on).

Numerical Error Codes

Message on printer display What it means What to do
13.XX PAPER JAM [LOCATION] Media is jammed at the specified location (and possibly at other locations). If the message persists after all jams have been cleared, a sensor or sensor lever might be stuck or broken.

For all jam messages, do the following:

1. Remove jammed print media from the specified location. Check the entire paper path for other pieces of media in the path.

2. Open and close the top cover to clear the message.

3. Check sensors and flags in the paper path for proper operation.

13.0 PAPER JAM [LOCATION] A non-specific paper jam occurred.

1. Remove jammed media from the specified location.

2. Verify the paper tray is fully closed.

3. Inspect and/or replace the feed and separation rollers.

4. Ensure there is no obstruction in the path, such as a torn piece of paper.

5. Open and close the top cover to clear the message.

6. Check sensors and flags for proper operation.

13.1 PAPER JAM OPEN INPUT TRAYS Paper-delay jam at paperfeed area. 1. Ensure that paper trays are loaded and adjusted properly so media can feed from the tray. It might be necessary to reduce the stack height of media in the tray.

2. Check the input area for obstructions such as media in the path. Also check to see if the registration assembly damaged or unseated.

3. Replace any defective sensors or flags.

4. Verify the media meets the specifications.

2. Replace any defective sensors or flags.

3. Ensure the media does not exceed the maximum length.

4. If multiple sheets are feeding, it might be necessary to fan the media and reduce the stack height. Also, replace separation pad.

5. Verify that the fuser is properly installed.

13.20 PAPER JAM CHECK REAR DOOR Media stopped in the paper path during power on or when the top door was closed. 1. Remove all media in the paper path, and then open and close the top cover.

2. If the message persists after all media is removed: Check if media is jammed in the prefeed area. Replace any defective sensors or flags

13.21 DOOR OPEN JAM The top cover was open while printing 1. Clear the jam and close the top door.

2. If the message persists, check the top door switch for proper operation.

13.5 PAPER JAM CHECK REAR DOOR Paper-delay jam at fuser. 1. Check the transfer roller and small media belt to ensure they are operating and can feed print media into the fuser.

2. Check the paper path for obstructions near the transfer roller, toner cartridge, paper feed assembly, and fuser.

4. Try removing and reseating the fuser.

5. Examine the fuser gears and drive gears for wear.

6. If needed replace fuser or appropriate drive gears, or both.

4. Ensure there is no obstruction in the path, such as a torn piece of paper.

5. Open and close the top cover to clear the message.

6. Check sensors and flags for proper operation

20 INSUFFICIENT MEMORY The printer received more data than can fit in available memory. You may be trying to print a document that is too complex for the printer’s capacity (too many macros, soft fonts, or graphics). Pressing GO may print the transferred data, but data may be missing or skewed.

If the file size of the print job exceeds printer’s onboard memory capacity, try adding more memory. Sometimes mismatched software drivers over-inflate the size of a document and cause these errors; you may want to download/install a different driver.

If all else fails, simplify the print job and print manageable segments at a time.

21 PAGE TOO COMPLEX The data (dense text, rules, raster or vector graphics) sent to the printer is too complex Pressing GO may print the transferred data; but some data may be missing or skewed. More memory may help.

Try a different driver, or simplify the print job by breaking it up into manageable segments.

40 EIO x BAD TRANSMISSION The connection has been broken between the printer and the EIO card in the specified slot. (Data loss might occur in this situation.) 1. Press GO to clear the error message and continue printing.

2. Reseat the EIO card in slot corresponding to [X].

3. Check cabling.

4. Replace the network card if needed.

5. Try a different software driver.

41.3 UNEXPECTED PAPER SIZE The printer detected a media size different from what it was expecting. This is typically caused if two or more sheets stick together in the printer or if the tray is not properly adjusted. 1. Reload the tray with the correct print media size.

2. Ensure that media in the tray is loaded under the front and back retaining tabs.

3. If you are printing from tray 1, verify that the correct paper size is selected in the control panel.

4. If you are printing from tray 2, 3, or 4, verify that any paper-size adjustments (length guide, width guide, size-selector switch) on the paper tray have been made correctly. Make sure the media is under the corner tabs.

5. After performing the actions above, press GO. The page containing the error will automatically be reprinted if jam recovery is enabled. (Or, you might want to press CANCEL JOB to clear the job from the printer’s memory.)

For the 4000, 4050, and 4100 series the paper feed assembly could be bad. Also the paper feed/registration sensors could be knocked out of place. On EX engine printers this error is caused by a bad PIU (paper input unit).

41.5 PRINTER ERROR The media reached the PS102 or PS103 sensor too early. 1. This error usually occurs with smooth media, such as transparencies or labels. If the problem persists when using tray 1, load media one sheet at a time. If the problem persists when using trays 3 and 4, replace the feed and separation rollers.

2. Check sensors PS102 and PS103 for proper operation.

For the 4000, 4050, and 4100 series the paper feed assembly could be bad. Also the paper feed/registration sensors could be knocked out of place. On EX engine printers this error is caused by a bad PIU (paper input unit).

41.x PRINTER ERROR A temporary printing error has occurred. The page containing the error will automatically be reprinted. If the error persists:

1. Reseat the connections to the laser scanner and then to the engine controller board.

2. Replace the laser scanner.

3. Replace the engine controller board

49.XX PRINTER ERROR A firmware error occurred 1. Press CANCEL JOB to clear the print job from the printer memory.

2. Turn the printer off, and then turn the printer on. You can try reprinting the job to see if it was a temporary error.

3. If error persists, try printing a job from a different software application. If the alternate job prints, go back to the first application and try printing a different file. (If the message only appears with a certain software application or certainprint job, try upgrading the printer driver and / or firmware.)

4. If the message persists with different software applications and print jobs, disconnect all cables to the printer that connect it to the network or printer. Turn the printer off and delete the print queue. Then reboot printer AND computer, reconnect cables, and try printing again.

5. Remove all EIO devices from the printer (JetDirect cards, hard drives, etc.). If 49 error goes away, turn printer off, re-install EIO devices one at a time, and reboot printer each time to determine which EIO device is failing.

6. If printing still fails with all EIO devices removed, remove all memory DIMMs or third-party DIMMs from the printer. (Do not remove the firmware DIMM– printer won’t function without this installed.) Turn the printer on with DIMMS missing. If the error no longer exists, install each DIMM  one at a time, turn printer on, test printer. Replace a DIMM if you determine that it causes the error.

7. Remember to reconnect all cables that connect the printer to the network or computer.

8. If the error persists, replace the firmware DIMM.

9. If error persists, replace the formatter.

2. Open the top cover and remove the toner cartridge.

3. Remove all the visible media.

4. Leave the printer turned off and remove the fuser to remove any remaining print media.

PERFORM PRINTER MAINTENANCE To ensure optimum print quality, the printer prompts the customer to have routine maintenance installed Install the printer maintenance kit. You must reset the maintenance page count after performing printer maintenance. Note The printer maintenance kit is a consumable item and is not covered under warranty
PROCESSING CLEANING PAGE The printer is conducting the manual cleaning-page process. Wait for the job to finish. This can take up to

2.5 minutes.

PROCESSING JOB The printer is processing a job Wait for the job to finish. This can take several minutes for a complex print job. If the printer “hangs up” on processing a job then it could be a bad formatter board.
RAM DISK DEVICE FAILURE The RAM disk had a critical or fatal failure. 1. Reseat the RAM disk.

2. Replace the RAM disk.

RAM DISK FILE OPERATION FAILED The requested operation could not be performed (for example, attempting to download a file to a nonexistent directory). 1. Check the filename and directory name.

2. Reseat the RAM disk.

Depending on how the printer has been configured in the configuration menu, it will either continue to print or stop. If the printer has stopped, you can resume printing by pressing GO for each job.

The high voltage power supply could also cause this error.

TONER OUT The toner cartridge has run out of toner. Depending on how the printer has been configured, it will either continue to print or stop. Due to the resolution of the toner level sensor, it is possible that a small amount of toner (less than one percent) might still be present in the cartridge. If the printer has stopped, you can resume printing by pressing GO for each job.

Replace toner cartridge. The high voltage power supply could also cause this error.

TRAY [X] EMPTY [TYPE] [SIZE] The specified tray is empty, but the current job does not need this tray in order to print correctly. If this message appears and the tray contains print media, a sensor could be damaged. 1. Load the empty tray (x) to clear the message.

10 Common Printer Faults

A printer in Berkshire needing Repair

This article lists the top 10 common printer faults our engineers encounter with general office laser printers.  By knowing the most common printer faults that can occur, you can reduce the amount down time that is caused as a result of these problems.

The Most Common Printer Faults

1. Paper JamsAnother laser printer in Berkshire with a paper jam to be repaired

A paper jam is the most frustrating and common printer fault our customers see and it seems to always happen when you are in a hurry. You open every door and flap to find where the paper jam is located and clear everything you find but it happens again. Paper jams are most often due to worn rollers and dust / dirt inside the printer but can also be caused by faulty fuser units and other consumables like a damaged transfer belt.

2. Print Quality Problems

Print quality issues are most often caused by a faulty or nearly empty toner cartridge.  Check the toner levels are not running low and also make sure the printer and printer driver is not using Economy mode, Draft mode or Grayscale. Lastly, take the toner cartridge out and give it a gentle shake and try printing again. If the problem persists, replace the toner/s to make sure they are not the cause.

3. Ghosting / Repeating

Ghosting is where you see the image repeating faintly down the page, Check the drums, transfer belt and fuser unit for damage. If possible, change the drums / toners to to make sure they are not the cause.

4. Image is dusty and comes off onto your fingers

If this happens on any part of your printed page, your fuser unit is not properly bonding the toner to the page and probably needs to be replaced. The fuser unit normally needs replacing every 50000 prints but exact page counts depend on the model of the printer.

5. Marks on pages when you use the copy button but not when you print from the computer

If you are seeing marks on your prints when you copy pages, the most likely cause will be dirt or marks on the scanner glass. Check the glass for dirt and correction fluid and gently clean with a soft cloth. Some ADF units use a plastic film which must be replaced when they become worn. If you see dirt is on the inside of the glass, it is advisable to have an engineer strip and clean your printer and scanner for you.

6. Blank Pages

If you have recently changed a toner cartridge, check that you have properly removed the tape and any shipping inserts from the new toner cartridge.

7. My printer is making a rattling noise

Grinding, rattling and graunching sounds can be caused by worn toners and drums. Replace the toners or drums to to make sure they are not the cause. If the noises persist, a cog inside the printer has perhaps become worn and will need to be replaced.

8. My Printer is not printing

If you printer is not printing and there is no error message you will need to check the printer is properly connected. If you are using a USB connection or hard wired network connection, check the cables are plugged in and do not show any signs of damage.
For Wi-Fi printers, double check Wi-Fi is enabled on both the printer and the PC / tablet. If all appears OK there, fully reinstall the drivers and software for the printer. Next check the printer user manual’s trouble shooting section. Lastly, check any firewall settings on your PC as these have been known to interfere with printer traffic.

9. Printer is running low on toner or ink.

As long as the printed pages are clean then just carry on printing as normal. Make sure you have spare toner cartridges just in case the printer does run out earlier than expected. Toner and ink cartridges often print for a while after they are due to expire but some will stop when the counter reaches its maximum.  Depending on the printer make and model, this can sometimes be overridden.  Check the user manual for details and where possible, try to refrain form swapping toner cartridges between printers.

10. Wi-Fi printing takes too long to print

Wi-Fi issues can be intermittent and difficult to solve.  Firstly, remove all sources of interference such as Microwave ovens and other electrically noisy devices.  Try placing the printer closer to the wireless router and see if this reduces the printing time. If this solves the problem, consider getting a wireless range extender or additional access point. You could also make sure your router’s firmware is up-to-date and that it supports 802.11n.
