HP Printer Error Codes



When some messages appear (for example, requests to load a tray or a message that a previous print job is still in the printer memory), you can press √ (Select button) to print, or to press Stop to clear the job and eliminate the message.

Error MessagesSolution
02Warming Up. This is commonly associated with printer cable or driver problems.
10Supplies Memory Error. Your printer has a problem with the toner cartridge chip, which it's unable to read. This is the electronic information, or e-label, on the print cartridge.
11 Paper Out. If your printer isn't out of paper, this probably means there's a problem with the paper tray or paper sensor.
12Open or No EP. If you printer does have toner cartridges installed correctly, this means either a cover is open or you may have defective cooling fans or PS5 sensors.
13Paper Jam. Your printer has a paper jam. Paper jams can occur at four stages: pickup, printing, fusing and exit. Modern HP printers will indicate where the jam has occurred. If using thick paper, check the HP paper guide for your printer.
14No EP Cartridge. Your printer either doesn't have a toner cartridge installed or doesn't recognise one that is.
16Toner Low. This normally means that your toner cartridge is either low on toner or empty. However it may mean that the remaining printer toner isn't distributed evenly.
20Memory Overflow. Your print job exceeds the current memory capacity of the printer.
21Print Overrun. Your print job exceeds the current memory capacity of the printer.
22I/O Configuration. There's a communication problem between the printer and the computer.
24 Job Memory Full. Too many print jobs have been send to the printer, or the job is too complex for the printer memory to process.
25XXX Memory Full. Too many print jobs have been send to the printer, or job is too complex for the printer memory to process.
30PS Error 16. This is commonly associated with PostScript firmware errors. It may also be triggered by PCL files being sent while the print is in PS mode or a bad PostScript file.
30.1.1Disk Failure. Your printer's hard disk drive has crashed.
40Data Transfer Error. The connection between the computer and printer has been broken.
41Temporary Print Engine Error. The printer has experienced a temporary printer engine error, which can normally be easily resolved.
49Printer Error or Communication Error. There can be a few causes of this error depending on the model, which tend to be associated with firmware errors, cable problems or hardware issues.
50.xFuser Error
50.1Low temperature. Fuser is failing to warm up.
50.2Warm up failure. The warm-up period timed out. This could be a power supply or firmware issue.
50.3High temperature. The main thermistor is too hot. Likely to be a control circuit issue.
50.4Faulty fuser (or Bad AC line voltage). Moderately likely to be bad mains supply (UPS, generator, extensions)
50.5Inconsistent fuser or Wrong type fuser installed. The printer has detected the wrong fuser.
50.6Open fuser. Fuser heater cut-off. The fuser possibly overheated.
50.7Fuser pressure release mechanism failure.
50.8 Lower fuser temperature (sub-thermistor).
50.9High fuser temperature (sub-thermistor).
51Beam Detect Error
52Incorrect Scanner Speed Error. The printer uses a polygon mirror to reflect the laser beam across the imaging unit.
54Printer Error Cycle Power. There are many causes for this error code.
55Internal Communication Problem / Controller Error. Most likely a poor connection between the DC controller and the formatter.
56Printer Device Error. This error message can relate to a number of different issues depending upon the model.
57.xx Fan Failure / Gears Seized / Memory Card Error
58.xxThere are many causes for this error code, depending upon the model it can mean: environmental sensor error, memory controller problem, fan problem, power problem or DC controller fault.
59 Motor Error
60.xxOn new printers this relates to a motorised tray lift error.
61Formatter , Memory Error
62Memory Error, Defective Formatter Board
63Defective Formatter Board
64Scan Buffer Error
65Scan Buffer Error
66 External Paper Handling Device Error
67Service Printer Error or Memory Error
68 Error in NVRAM. Service Error NVRAM full
69Duplexer Error has Occurred
70Faulty MIO Card or SIMMs or Wrong Cartridge
71Faulty MIO Card or SIMMs or Wrong Cartridge
72Defective Font Cartridge or Formatter Board
79Critical Hardware Error has Occurred
80Defective Network Card or Formatter Board
81Defective Network Card or Formatter Board
89PostScript ROM Failure
99Firmware Upgrade
10.XX.YY1. Turn the printer off, and then turn the printer on to clear the message. 2. If the message persists, open the top cover, remove the print cartridge, and then reinstall it. 3. If the message persists, install a new HP print cartridge. 4. If the message persists, check the connection between the ECU and the memory chip on the print cartridge.
49.XXXXXA critical firmware error has occurred.
51.XYA temporary printing error occurred.
53.XY.ZZCheck Ram Dimm Slot. A problem exists in the printer memory. The DIMM that caused the error will not be used
54.XXThis message is typically related to a sensor issue.
55.XX.YYDc Controller Error
56.XXA temporary printing error occurred as a result of an incorrect input or output request.

Printer resets and power-on modes

The following sections describe the types of printer resets and power-on modes.




Cold reset

A cold reset unlocks menus that have been previously locked and sets all control panel menu items (including EIO settings) back to the factory defaults. However, it does not clear the values in the service menu (such as the serial number and page counts).

To perform a cold reset:

  1. Turn the printer off.
  2. Turn the printer on. When the printer begins its memory count, press and hold down the Select ( √ ) button until all three printer control-panel lights flash once and then remain on. This might take up to 10 seconds.
  3. After the message SELECT LANGUAGE appears on the display, press the Up Arrow ( Λ) button
    or the Down Arrow (∇ ) button until COLD RESET is highlighted.
  4. Press the Select ( √) button. The printer performs a cold reset and then continues its power-on sequence.
  5. Check all I/O settings and reset any customer-set printer configuration values.

EIO Troubleshooting

If the printer contains an optional HP Jetdirect print server, and you cannot communicate with the printer over the network, verify that the print server is operating. Print a configuration page (see Configuration page on page 146). If the Jetdirect card does not appear under “Installed personalities and options” on the configuration page, reseat or replace the Jetdirect EIO card. See the troubleshooting section of the HP Jetdirect Print Server Software Administrators Guide.

When the HP Jetdirect print server is installed correctly, print a Jetdirect page (this page automatically prints when a Jetdirect print server is installed and a configuration page is printed). The Jetdirect page contains valuable network-related information about the printer.

If the host system and printer are still not communicating, replace the formatter (see Formatter on page 89) and the EIO card, and then reconfigure the printer.

The following illustration shows the contents of the Jetdirect page.

If media is feeding incorrectly, use the information in this section to identify and resolve the problem.

Multiple pages feed – Cause and Solution




  • The tray 1 separation pad is worn. Replace the tray cassette.
  • Too much media (particularly envelopes) is loaded in tray 1. Remove some of the media and resend the print job.
  • The media pick-up roller for that tray is worn or damaged Replace the pick-up roller.
  • The media edges are locked together. Flex the media stack before loading it into the printer. Do not fan the media.
  • Tray 2 is defective. Replace the tray.
  • The spring pushing the separation pad assembly is defective. Replace the tray cassette.

Pages are wrinkled or folded – Cause and Solution

  • The feed rollers or registration rollers are dirty or defective. Replace the affected rollers.
  • The paper path contains foreign substances or dirt. Remove any foreign substances or dirt from the paper path.
  • The cartridge shutter open/close mechanism is damaged. The shutter in the print cartridge should open as you insert the cartridge. If a shutter does not open, replace the print cartridge.
  • The registration assembly is defective. If the registration arm is dirty, clean it.
  • The fuser inlet guide is dirty. Replace the fuser.
  • The fuser pressure roller is dirty or damaged. Run several cleaning pages through the printer.

Pages are skewed – Cause and Solution

  • Paper dust or dirt has accumulated on the media pick-up separation roller. Clean or replace the separation roller.
  • The media pick-up roller may be worn irregularly. Replace the affected roller and separation pad assembly.
  • The registration assembly is defective. Replace the registration assembly.
  • Tray 2 is defective. Replace tray 2.
