Diagnostic Information 4
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 flashing operator panel lights. A
flashing Draft light always indicates a service related error. If your
machine has an error indication, locate the pattern of alternating
flashing lights in the following table and take the indicated action.
If your machine does not have an error indicator, go to “Power-on-
self-test (Post) Sequence” on page 7. 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 26.
2. The error is the last number to print on the page in the lower right
corner. Note the number.
3. Run “Initialize Nvram” on page 28 to clear the log (the number
may not be the result of a current error).
4. Run Test Page again to verify a current error. If no error prints,
go to “Power-on-self-test (Post) Sequence” on page 7.
