Introduction

This chapter covers the general start-up, Power On Self Test (POST), and power
supply operations of the printer to aid in troubleshooting problems not associated with
a front panel error message or error code. For troubleshooting problems associated
with an error code or front panel error message, notes on how to use the
troubleshooting procedure tables, and how to use service diagnostics, see Chapter 3
"Error Messages and Codes" on page 3-1. The Printer Status page also contains useful
troubleshooting information. This page provides general printer information, life
information for all consumables, color registration/calibration information.
Troubleshooting procedures will isolate a problem to a specific component or
subassembly, in some cases including the wiring harness. If you go through the
procedures in a troubleshooting table and still are unable to solve the problem, re-read
the Theory of Operations for the problem area and ensure that you understand how
that section of the printer is supposed to function.

The Printer Status Page is a two page printout that provides a great deal of useful
