Introduction; Preliminary Procedures - Xerox 3450B - Phaser B/W Laser Printer Service Manual

Introduction

This chapter covers the general start-up, Power On Self Test, and power supply
operations of the printer to aid in troubleshooting problems not associated with an
error code or front panel error message. 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.
Troubleshooting procedures will isolate a problem to a specific component or
subassembly, in some cases including the wiring harness.
