ABOUT THIS MANUAL

This manual contains Repair Analysis Procedures, Repair Procedures, Adjustment Procedures, Parts List, Diagnostic Procedures, and Wiring Data information that will enable a Service Representative to repair the XJ6C Printer.

ORGANIZATION

This manual is divided into seven sections. The title and description of each section is listed below.

A Publication Comment Sheet is provided at the end of this manual.

Section 1 - SERVICE CALL PROCEDURES

This section contains the following:

• Initial Actions / System Checks

• System Checkout

• Final Action

Initial Actions / System Checks

This diagram identifies how to collect the data necessary to decide how to proceed with the service call. It classifies the problem and refers you to the appropriate Repair Analysis Procedure.

System Checkout

The System Checkout procedure is used to verify that the printer is operating properly after a repair has been made.

Final Action

The Final Action procedure identifies the steps that must be performed before finishing the repair.

Section 2 - REPAIR ANALYSIS PROCEDURES (RAPs)

This section contains the Repair Analysis Procedures (RAPs) necessary to repair faults. When using a RAP, always exit the procedure when the fault is fixed. Do not perform the remaining steps.

Section 3 - IMAGE QUALITY REPAIR ANALYSIS PROCEDURES (RAPs)

This section contains the Repair Analysis Procedures (RAPs) necessary to repair print quality faults. The first RAP, IQ 1 Image Defect Entry RAP, is used to classify a print quality problem and will reference the RAP to be used to repair the problem. When using a RAP, exit the procedure when the fault is fixed. Do not perform the remaining steps.

Section 4 - REPAIR / ADJUSTMENT PROCEDURES

This section contains the repair and adjustment procedures for the XJ6C Printer.

Section 5 - PARTS LIST

This section contains the detailed Parts List for the XJ6C Printer.

Section 6 - GENERAL PROCEDURES

This section contains Diagnostic Procedures and Product Specifications for the XJ6C Printer. An XJ6C Printer Overview and Technical Overview section are also included.

Section 7 - WIRING DATA

This section contains Plug/Jack Location Drawings and BSDs.

HOW TO USE THIS MANUAL

The Service Call Procedures will direct you to the proper section of the Service Manual.

You should begin the service call with the Initial Actions / System Checks Procedure. From there, you will be referenced to either Section 2, Status Indicator RAPs or Section 3, Image Quality RAPs.

If you are sent to Section 3, you will perform the IQ 1 Image Defect Entry RAP to classify the print quality problem. You will then be directed to the proper RAP to begin your troubleshooting. From these RAPs you may be referenced to other sections of the manual to make checks, adjustments or to replace parts.

When you have made a repair, return to the System Checkout / Final Action to complete the call.
