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
lolerances are used within this section:
