HP LaserJet Printer Cleaning

By cleaning your HP laser printers, you’re sure to lengthen your printer’s life and avoid the troubles of printer malfunction caused by not performing the task mentioned. Most printer users tend to search the internet on how-to’s but end up finding complicated steps that’s why in this article, we’re going to show you three ways on how to clean that HP laser printer as easy as a piece of cake.

  • Cleaning the HP Laser Printer’s surface – When your HP laser printer’s surface gets dusty, you can just wipe it off the top using anti-static wipes or a paper towel, or use a can of compressed air and spray the top, removing the dusts.
  • Cleaning the Inside of Your HP Laser Printer – On the inside, the same compartment where you place your HP toner cartridges in, simply remove the cartridge then use compressed air to blow any dust particles stuck in the toner tray. If you see any large particles of paper that came from paper jams, pull out the remaining parts of papers before putting the toner cartridge back to its place.
  • Cleaning the Slot of the Paper Tray – That part can accumulate dusts too, so its better to clean it up as well by  first taking out the paper tray then the same as the printer’s surface, you use anti-static wipes, paper towel or compressed air to get the dusts off the printer.

HP LaserJet Error Codes

Message on Printer Display Panel What it means. What to do. Additional comments.
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.
  • Remove jammed print media from the specified location. Check the entire paper path for other pieces of media in the path.
  • Open and close the top cover to clear the message.
  • Check sensors and flags in the paper path for proper operation.
3.0 PAPER JAM [LOCATION] A non-specific paper jam occurred.
  • Remove jammed media from the specified location.
  • Verify the paper tray is fully closed.
  • Inspect and/or replace the feed and separation rollers.
  • Ensure there is no obstruction in the path, such as a torn piece of paper.
  • Open and close the top cover to clear the message.
  • Check sensors and flags for proper operation.
13.1 PAPER JAM OPEN INPUT TRAYS Paper-delay jam at paperfeed area.
  • 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.
  • Check the input area for obstructions such as media in the path. Also check to see if the registration assembly damaged or unseated.
  • Replace any defective sensors or flags.
  • Verify the media meets the specifications.
  • Check the pickup feed and separation rollers for unusual wear.  Replace as needed.
  •  Rotate the media in the input tray by 180° and/or turn it over
On NX engines this is most likely the fuser flag or the ACPM. The ACPM has a photosensor hard-wired to the back of it.
13.10 PAPER JAM CHECK DUPLEXER Jam at duplexer.
  • Check the duplexer and the rear area of the printer for obstructions or damage.
  • Check the duplexer for proper operation. Replace the duplexer if a sensor is defective.
On a 5si, 8000, or 8100 series laserjet a Duplex Jam can be caused by a tray 2 and 3 feed assembly failure.
13.14 For Laserjet 5si. This error is caused by a defective paper control PCA

Replace paper control PCA.

13.2 PAPER JAM OPEN INPUT TRAYS Paper-stopped jam at paper-feed area.
  • Check the input area for obstructions such as paper in the path. Also check to see if the registration assembly is damaged or if the transfer roller is out of place.
  • Replace any defective sensors or flags.
  • Ensure the media does not exceed the maximum length.
  • If multiple sheets are feeding, it might be necessary to fan the media and reduce the stack height. Also, replace separation pad.
  • Verify that the fuser is properly installed.
On NX engines this is an input jam.
13.20 PAPER JAM CHECK REAR DOOR Media stopped in the paper path during power on or when the top door was closed.
  • Remove all media in the paper path, and then open and close the top cover.
  • 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.
  • Clear the jam and close the top door.
  • If the message persists, check the top door switch for proper operation.
13.5 PAPER JAM CHECK REAR DOOR Paper-delay jam at fuser.
  • Check the transfer roller and small media belt to ensure they are operating and can feed print media.
  • Check the paper path for obstructions at the transfer roller, toner cartridge, paper feed assembly, and fuser.
  • Replace any defective sensors or flags.
  • Turn the media stack over and/ or rotate it by 180° in the input tray.
If still persists - replace fuser, then DC controller.
13.6 PAPER JAM CHECK REAR DOOR Paper-stopped jam at fuser.
  • Check the paper path for obstructions at the fuser and output/delivery area.
  • Replace any defective sensors or flags.
13.99 PAPER JAM [LOCATION] A non-specific paper jam occurred.
  • Remove jammed media from the specified location.
  • Verify the paper tray is fully closed.
  • Inspect and/or replace the feed and separation rollers.
  • Ensure there is no obstruction in the path, such as a torn piece of paper.
  • Open and close the top cover to clear the message.
  • Check sensors and flags for proper operation
20 INSUFFICIENT MEMORY The printer received more data than can fit in available memory.

You might have tried to transfer too many macros, soft fonts, or complex graphics. Press GO to print the transferred data (some data might be lost). Advise the customer to simplify the print job or install additional memory

21 PAGE TOO COMPLEX The data (dense text, rules, raster or vector graphics) sent to the printer is too complex

Press GO to print the transferred data. (Some data might be lost.) Advise the customer to simplify the print job.

More memory might help.
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.)
  • Press GO to clear the error message and continue printing.
  • Reseat the EIO card in slot [X].
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.
  • Reload the tray with the correct print media size.
  • Ensure that media in the tray is loaded under the front and back tabs.
  • If you are printing from tray 1, verify that the correct paper size is selected in the control panel.
  • If you are printing from tray 2, 3, or 4, verify that the three 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.
  • 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.
  • 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.
  • 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
  • Press CANCEL JOB to clear the print job from the printer memory.
  • Turn the printer off, and then turn the printer on.
  • Try printing a job from a different software application. If the 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 print job, contact the software vendor for assistance.)
  • 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.
  • Remove all memory DIMMs or third-party DIMMs from the printer. (Do not remove the firmware DIMM in the lowest DIMM slot.)
  • Remove all EIO devices from the printer.
  • Turn the printer on.
  • If the error no longer exists, install each DIMM and EIO device one at a time, making sure to turn the printer off and back on as you install each device.
  • Replace a DIMM or EIO device if you determine that it causes the error.
  • Remember to reconnect all cables that connect the printer to the network or computer.
  • If the error persists, replace the firmware DIMM.
  • Replace the formatter.
This error is usually caused by a bad formatter board.
