Introduction; Servicing Instructions - Fuji Xerox Phaser 5500 Service Manual

Introduction

This chapter describes the printer's self-diagnostic capabilities and includes methods
to identify and remedy reported printer problems. The diagnostic routines report
problems using error messages and fault codes displayed on the Front Panel, logged
in the Service Usage Profile, listed on the Startup Page or by flashing LEDs. These
error indications serve as the entry point into the troubleshooting process. Printer
problems not directly indicated by or associated with an error message or fault code
are covered in Chapter 4, "General Troubleshooting." Print-quality problems are
covered in Chapter 5, "Print-Quality Troubleshooting."
