Introduction
The Primary Error Code List should be used whenever an error code
occurs during a terminal operation or a self test. The list identifies a
replaceable component (or components) for a code, or directs you to
perform a RAP to isolate the problem.
If an operation fails, sometimes the terminal will generate a four-digit
sub code, rather than a primary error code. When this occurs, you
should refer to the Sub to Primary Error Code Cross Reference to identify
the related primary code, then repair the problem according to that
code.
The Repair Analysis Procedures (RAP) section is used to isolate an
identified problem to a faulty component or subassembly. This section
is accessed through Section 1, Service Call Procedures. Because the RAPs
are built on one another, you should not use them without going
through Section 1 first.
Some of the RAPs require you to measure voltages to isolate a problem.
When voltage test points are provided, connect the red meter lead to
the first test point, and connect the black meter lead to the second test
point.
NOTE: All meter ranges and readings are referenced to the Xerox
digital meter (600T1616). These ranges and readings may not be valid
with other meters.
When a problem has been isolated to a faulty component or
subassembly, first check for loose, bent, or dirty connections as the cause
of the problem. If one of these is the cause, always attempt to resolve
the problem by tightening connections, straightening bent pins, or
cleaning contacts prior to replacing components.
CAUTION
To prevent damage to the hard disk drive, disconnect the power cord
and wait ten to fifteen seconds before moving the terminal.
