Designjet Plotter Error Codes

The HP Designjet error code displayed on your large format (wide format) printer e.g. does not always provide an exact indication of the problem or issue - and you (the user) will often be unable to diagnose or fully resolve the Designjet fault yourself - even with the error code information provided here.  

HP Designjet error codes are not an exact science. They exist to help the engineer diagnose key areas for assessment, and can often indicate one or more parts have failed. It is not unknown for HP engineering manuals to omit reasons for certain error codes (or even omit the error codes themselves!). This is where it pays to engage experts in the field of HP Designjet repairs so that you receive the fastest and most cost effective fix. Based upon the reported fault, a trained and qualified HP Designjet engineer will usually work through a pre-defined set of tests and apply many years of working knowledge to effect the fastest repair - choosing those parts first which he knows will usually resolve the fault rather than systematically working through the manual.

System Error

Use the power switch at the rear to turn off the printer, then disconnect the power cord. Reconnect the power cord, then turn on the printer.

Make sure that the paper path is clear. If necessary, carefully unload the media and reboot the printer.

If there is no sign of a physical paper jam then a hardware failure could be causing the issue:

  • Worn carriage belt
    • Over time the rubber carriage belt which drives the carriage assembly can become worn. The belt will either become slack or the teeth will be shredded. Open the window to check if the carriage belt is slack or if there is a build-up of rubber debris inside the printer.
  • Carriage rod
    • The carriage rod is the small metal bar running the width of the printer which the carriage 'slides' along. This carriage rod needs to be kept clean & lubricated to allow free movement of the carriage. (You must only use HP lubricant)
  • Dirty or damaged encoder strip
    • The encoder strip is the thin metal strip which runs the width of your printer & on most models is located just above the slider rod. The printer uses the encoder strip to calculate the carriage position on the scan-axis. If the encoder strip is damaged or dirty then the encoder sensor will have issues recognising the encoder strip position. Carefully clean the encoder strip with non-abrasive liquid and a lint-free cloth. (Be careful, the encoder strip is sharp.)
  • Service Station
    • Check the service station for blockages that could restrict the movement of the carriage.
  • Carriage Latch
    • Make sure the carriage latch/cover is correctly closed.
