HP LaserJet family printer error codes.

This page is presented as a public service. I am only a channeler of information and DO NOT service laser printers. Please DO NOT Email for assistance in troubleshooting problems. In the Atlanta area I recommend Atlantis Laser (770-717-8017) as a very knowledgeable and competent laser repair source. People who I have referred to them have always indicated that their problems were fixed in a timely manner and fairly priced.

Some of the checkpoints referred to in this document require special tools or meters as well as familiarity and training on laser printers. There are LETHAL voltages inside of a laser printer and untrained personnel should refrain from doing anything other than determining that the error code in question is caused by a hardware failure and cannot be cleared by an operator.
