Error Troubleshooting

Introduction

This chapter covers the general startup and Service Diagnostics used to test system operation and
troubleshooting procedures to correct problems. Also discussed are error messages and numeric codes
displayed on the Control Panel or listed on the Error History Report.
The printer tracks and reports errors in a number of ways. The two types of error reporting discussed in
this chapter include:
• Error messages and Chain Link codes display on the Control Panel
• Engine (fatal) and Jam Error logs display on the Control Panel or listed on the Error History Report
Troubleshooting print quality problems are covered in Chapter 3
