Start

Use the error message table, symptom table, service checks, in this
chapter and the diagnostic aids in Chapter 3 to determine the
corrective action to repair a printer.
If the operator panel is blank, black or appears unusual, unplug the
video controller board and run the engine print tests using the
Density Adjustment Panel. Go to Chapter 3 "Diagnostic Aids" to start
the call since the operator panel or video controller board may have
a defect.
If an error is displayed, locate it in the following "error message
table" and take the appropriate action.
If your machine does not have an error code and does not complete
Power-On Self Test (POST), go to POST and the POST symptom
table. If your machine makes it through POST without an error but
you have a symptom, go to the symptom table, locate your symptom
and take the appropriate action.
If an error message appears while you are working on the printer, go
to the error message table and take the indicated action.
Note: Some of the following service checks require voltage and/or
continuity readings. For continuity readings, turn off and unplug the
printer or optional sheet feeder. For voltage measurements, close
the front door and be sure the door micro switch is in the closed
position.
WARNING: It is possible for the printer to enter POST or print tests
with all covers removed (except the front cover) and the door switch
closed.
