Preface

This service manual is designed to be used by printer repair
technicians during servicer training and when repairing a failing
printer. The technician should first understand the failing symptom.
Then begin at “Start” (page 2-1) in this service manual and follow the
steps to diagnose and fix the failure.

This manual is divided into the following chapters:

1. “General Information” introduces the printer.

2. “Diagnostic Information” includes the procedures that give you

step-by-step instructions to isolate the failing FRU.

3. “Diagnostic Aids” includes test procedures that are used to

diagnose problems and test the machine after repairs have been
made.

4. “Repair Information” shows how to change the failing FRU and

make necessary adjustments.

5. “Connector Locations” shows how to find test points and

illustrates the paper paths and ink supply system.

6. “Preventive Maintenance” includes suggestions for maintaining

the printer.

7. “Parts Catalog” lists the part numbers for the FRUs.
