HP LaserJet Printer Error Codes

If your HP LaserJet printer has stopped working then it will probably also display an error message. These error messages are there to help you troubleshoot and repair yours LaserJet’s fault. Different models have slightly different wording for the error, but the troubleshooting tips are generally the same.

Common HP Printer Error Messages

Many HP printer error messages are common amongst the range, both old and new. Many, such as 11 – Paper Out, may seem fairly self-explanatory but could actually be the result of something else. Here’s our quick guide to the most common HP printer error codes, what the error codes mean and how to fix them.  

HP Error Code:

02 - Warming Up

Explanation:

This is commonly associated with printer cable or driver problems.

What to do:

Turn off the printer and remove the printer cable (USB or I/O cable), then turn it back on. If the printer reports "Ready" then first update the driver, and if not resolved then the printer cable. If there is still an error, there may be a hardware problem.

HP Error Code:
