Maintenance Approach

The diagnostic information in this manual will lead you to the correct
field replaceable unit (FRU) or part. Use the error code charts,
symptom index, service checks, and diagnostic aids to determine
the symptom and repair the failure. Begin with “Start” on page 2-2.

This printer can be serviced without being connected to a host.

After you complete the repair, perform tests as needed to verify the
repair.
