Use the service error code, user status message, user error message, symptom table, service checks, and diagnostic aids in this chapter to determine the corrective action necessary to repair a malfunctioning printer.

They will lead you to solutions or service checks, including use of various tests.

Symptom tables

If your machine completes the

“Power–On Self Test (POST) sequence” on page 2-1

without an error and you

have a symptom, then go to

“Service error codes” on page 2-26

. Locate your symptom, and take the

appropriate action.

Service errors (8xx.xx / 9xx.xx’s)

If a service error code appears while you are working on the machine, then go to

“Service error codes” on page 2-26

, and take the indicated action for that error.

Service error codes are indicated by a three-digit error code followed by a period and additional numbers in the format XXX.YY. In most cases, five digits are shown.
