Procedures

This section contains Repair Analysis
Procedures (RAPS). You will be directed to
this section to isolate a faulty component or
subassembly.

Section 3

Image Quality Repair Analysis
Procedures

This section contains Image Quality Repair
Analysis Procedures (t0 RAPS) and Image
Quality samples. You will refer to this sectlon
to identify test pattern samples or isolation
procedures for common image quality
defects.

Sectlon 4

Repair I Adjustment

This section contains the instructions for
removal, replacement, and adjustment of the
spared parts within the machine.

Section 5

Parts List

This section consists of illustrations and part
number lists. Any part that is spared or any
pert that must be removed to access a spared
part is illustrated. Common hardware is
shown as a letter callout.

Section 6

General Procedures I tnformation

This section contains general procedures,
product specifications, supplemental tools
and supplies, Tag/MOD informalion. and
installation instructions.

Section 7 Wiring Data

This section contains illustrations and lists of
the signals and connectors. The illustrations
show the power, ground, and the control
signal distribution. The lists show the signals
and pin assignments for all connectors.

How to use this manual

Start all service calls and end all service calls with
the Service Call Procedures, Section 1. Perform
Initial Actions and the System Check to identify a
symptom.

Follow the instructions provided within the Service
Call Procedures and proceed to the appropriate
section of the manual.

After the repair is complete, verify the repair with
the System Check.

1 Service Call Procedures

Introduction

The Service Call Procedures section is used to
identify a suspected problem.

This section
contains Call Flow, tnitial Actions, System Checks,
Additional Checks, Subsystem Maintenance. and
Final Actions.

Initial Actions are used to gather information
regarding the performance of the machine and
prepare the product for servicing.

System Checks are used to verify the normal
operation of the machine. In the Y/N (Yes/No)
steps of the system checks, a Yes response will
lead you lo the next step. A No response will
indicate the next step to perform or will direct you
to a Repair Analysis Procedure (RAP).

Additional Checks test various machine functions
not directly tested by system checks.

RAPS will provide the instructions to isolate the
faulty part or provide a list of suspect parts, when
isolation is not appropriate. Wire harnesses are
not included in the repair actions and problems
with loose connections or damaged harnesses
should be isolated using visual inspection and the
wiring data in section 7.

Subsystem

Maintenance contains

routine

maintenance procedures.
Final Actions are used to evaluate the total

operation of the system and to identify the actions
required to complete the service call.

The Repair Analysis Procedures section is used
to isolate and identify problems to a faulty
component or subassembly. It contains the

Introduction, display message

table,
communication errw code table and the Repair
Analysis Procedures (RAPS).

The various tables include all operator messages
indicated in the display and their meanings. The
tables will also list the Transmit z&Receive error
codes and associated messages.

Use the Display Messages and Communication
Error Codes tables when messages are displayed
or error codes are printed in a report.

The Repair Analysis Procedures (RAPS) are
accessed from Section I, system checks or
additional checks. There are two types of RAPS:
Status Indicator (Sl) RAPS. contained in this
section, and Image Quality (IQ) RAPS, located in
Section 3.

RAPS will normally isolate a problem to a specific
component or subassembly, excluding the wire
harnesses.

In the Y/N (Yes/No) steps of the RAPS, a Yes
response will lead you to the next step. A No
response will indicate a corrective action. When

the indicated corrective action has been
completed, go to Section 1 and restart the System

Check to verify that the problem has bean

corrected.

Measurements

Power and signal grounds are connected to frame
ground, therefore all circuit troubleshooting can
be performed using the metal frame (chassis) as
the QrOundinQ point. lf more information is
needed to locate connectors or test points, refer
to section 7.

NOTE: Make all voltage to ground
unless instmcted to measum fmm “xx”

Unless otherwise specified , the following voltage
