Use standard fault isolation techniques to troubleshoot malfunctions that are
not indicated by display messages. These techniques are summarized
below:
1. Ask the operator to describe the problem.
2. Verify the fault by running a diagnostic printer test or by replicating
conditions reported by the user.
3. Look for a match in the General Symptom List that begins on page 67.
If you find a match, go to the troubleshooting procedure and follow the
numbered instructions.
4. If you do not find the symptom in the General Symptom List, use the
Half-Split Method to find the malfunction:
a. Start at a general level and work down to details.
b. Isolate faults to half the remaining system at a time, until the final half
is a field-replaceable part or assembly. (Troubleshooting aids are
listed on page 55.)
