Chapter 4 Failure & Repair Analysis

4.1 OVERVIEW

4.1.01 Introduction

This section is used to isolate problems to the assembly level. Application problems and detection of faulty

components on the printed circuit boards are not addressed.

When troubleshooting a defective unit, refer first to Section 4.4

of this Service Handbook.

This

section contains tips on preventing problems as well as a list of common problems.

Next, refer to Section 4.6. Repair Analysis Procedures

(RAPs)

will ask you questions or require you

to make observations. The answers to these questions and the results of your observations determine

your next course of action. Use the RAP Index to identify which RAP should be used to resolve the

problem with the machine.

If you encounter a situation that is not addressed by the documentation in this kit, please report the

problem to Okidata. Send your report to the Okidata Technical Training Group. Refer to the Service
