Use the error code charts, symptom index, service checks, and
diagnostic aids in this chapter to determine the failing part in a mal-
functioning printer.
Start
Service error indications show up as a series of flashes of the Power
On light. There is a pause between each series of flashes. If your
machine has an error indication, locate the series of flashes in the
following table and take the indicated action. Unplug the machine to
clear the error indicator.
If your machine does not have an error indicator, go to “Power-on-
self-test (POST) Sequence” on page 5 . If an error indicator appears
while you are working on the machine, go to the error indicator table
and take the indicated action for that error.
The printer also logs the last occurring error. If you think you may
have an intermittent error, or the error indicator lights have been
cleared, you can retrieve the error from the Test Page printout:
1. Run the “Test Page” on page 18 . The error is the last number to
print on the page in the lower right corner. Note the number.
2. Run “Initialize Error Log” on page 20 to clear the log (the number
may not be the result of a current error).
3. Run the Test Page again to verify a current error. If no error
prints, go to “Power-on-self-test (POST) Sequence” on page 5 .
