Guide to Troubleshooting the Printer
Introduction
This chapter will guide you through the relevant steps to take when
troubleshooting the printer.
Troubleshooting System Error Codes
Chapter 2 - System Error Codes contains a list of system error codes and
their respective descriptions and recommended corrective actions. Only try
one recommended action at a time and check if the error code has
disappeared.
If you have an error code which is not documented in this Service Manual or
you have an error which you cannot resolve, then report the error to the HP
Response Center or the nearest HP Support Office. When reporting the
error, have the following information ready:
îš„ Model and Serial Number of the printer.
îš„ Which firmware revision the printer is using (See Note below). Check
firmware in Utilities / Statistics / Code rev.
îš„ The complete error number (See Note below).
îš„ The Service Configuration Print.
îš„
The Current configuration sheet.
îš„ Which software application the customer is using (name, version, etc.).
When reporting the System Error Code, make sure that you
supply the full Error Code and the firmware version. Without
this information, HP Support Personnel cannot help you.
Performing a Service Test on a Failed Assembly
If possible, always perform a Service Test on the component/assembly that
you are about to replace, just to make sure that is the component/assembly
that has failed.
If the test on that component/assembly passes, you should
NOT replace it.
For information on the Service Tests and how to use them see Chapter 4 -
Diagnostic Tests and Utilities.
