This Troubleshooting Guide is provided to

malfunctions. Simply follow the three step
procedure below.
Step 1. LOCATE PROBLEM (SYMPTOM).
Look under the column labeled “PROBLEM
(SYMPTOMS)”. This column describes
possible symptoms that the machinery may
exhibit. Find the listing that best describes
the symptom that the machine is exhibiting.
Symptoms are grouped according to:
feeding problems and function problems.
Step 2. PERFORM EXTERNAL TESTS.
The second column labeled “POSSIBLE
AREAS OF MISADJUSTMENT(S)” lists the
obvious external possibilities that may
contribute to the machine symptom.
Perform these tests/checks in the order
listed. In general, these tests can be
conducted without removing the case wrap-
around cover.
Step 3. PERFORM COMPONENT TESTS.
The last column labeled “RECOMMENDED
COURSE OF ACTION” lists the most likely
components that may have failed in your
machine. It also specifies the appropriate
test procedure to verify that the subject
component is either bad or good. If there
are a number of possible components,
check the components in the order listed
to
eliminate one possibility at a time until you
locate the cause of your problem.
All the necessary test specifications and
repair procedures are described in detail
following the troubleshooting guide. All
electrical test points, terminal strips,
junctions, etc., can be found on the
electrical wiring diagrams and schematics
