repairing and maintaining the family of products. The manual contains this information divided into the following sections:

Section 1

Service Call Procedures

This section is used to identify the first audible or visual symptom for the problem. The procedures will then direct you to a RAP or they identify a faulty component or subassembly.

Section 2

Status Indicator Repair Analysis 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” to “xx

Introduction

The Image Quality (IQ) section is used to identify image quality problems.

It conlains the Introduction, Image Quality samples, and Image Quality RAPS.

The sample is a reproduction of the image quality

test pattern 82P151.

Compare the image quality of the samples produced in section 1, System Checks, with the 82P151 test pattern in your kit. This will identify

any image quality defects which may have been

produced during Off-line or On-line System Checks.

Use the Image Quality RAPS to further diagnose

machine problems. In the YIN C/es/No) steps of the RAPS. a Yes

response will lead you to the next step. A No response will indicate a corrective action, or will direct you to another step. When the ihdicated corrective action ‘has been completed, go to Section 1 and restart the Syste& Check to verify that the problem has been 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 grounding point.

If more information is needed to locate connectors or test points, refer to section 7.

NOTE: Make aft voltage measurements to ground unless instructed to measure from “W to “xx’:

Unless specified otherwise. the following voltage tolerances are used within this section:

Overview

The Repair I Adjustment section, Section 4 of the

Service Manual, provides information that enables the Service Representative to restore the product to within specification after fault isolation.

Section Contents

The Section Contents lists, in sequence, all the

items of the section, with page references. Each entry in the section contents appears exactly as it

appears in the manual.

Repair Procedures

This repair subsection contains instructions for

removal and replacement tasks. A removal and/or

replacement task is included when it is not obvious

how components are removed and replaced. or when special conditions (such as an adjustment)

must be met during these tasks.

Step-by-step removal procedures for a specific

component or assembly are provided. A good. general procedure to follow for most

repairs is to remove the handset and cradle. Also, disconnect all the modular cables from the

machine.

Illustrations are used to assist you with the

procedures. You should refer to the specific Parts

List illustration (listed under the repair title) for

locating most components within a procedure.

Adjustment

The adjustment subsection consists of a complete

set of instructions for performing independent adjustment tasks.

The title of each independent adjustment is in

boldface type. Under the title, the adjustment task contains the following sections:

Purpose

The Purpose of the adjustment task states the

reason for performing the adjustment.

Gflak

The Check defines the quickest way to determine

whether the adjustments are within specification.

A check is used only when it is possible to determine that the component is within specification without disturbing the adjustment.

The Adjustment contains complete instructions for

performing the adjustment task,.

Grid Adjust

Purpose

Ensures that the horizontal print alignment is

within specification.

NOTE: Figure 1 is an example of the test pattern printed in the Grid Adjust Mode.

The center Grid Line Set represents the current hodzontalpdnt alignment. The sets of Grid Lines above and below the center Grid Line Set are printed to assist in determining whether the cunent value should be changed in the pas [+j or the neg (-) direction.

Each vertical line is formed by three short lines. If the three lines we properly aligned, perfectly straight lines will be

printed. The adjustment moves only the

middle line of the three lines. The adjustment range is i32.

Adjustment

1. Enter the service mode and print the Grid Adjust pattern (Figure 1).

2. Check for correct vedical alignment of the center Grid Line Sei. If the check is good, exit the procedure.

3. Change the current value to a setting that will align the three short lines of the center grid line set.

a. Press

value.

b. Press
