CAUTION: Remove power from the printer before you connect or disconnect any cable, electronic board or
assembly, for personal safety and to prevent damage to the printer. Always use the hand grips on the side
of the printer and be sure your fingers are not under the printer when you set the printer down.
Use the service error codes, user status messages, user error messages, symptom tables, service checks,
and diagnostic aids, to determine the corrective action necessary to repair a malfunctioning printer.
Service error codes are indicated by a two-character alphanumeric error code. If a service error code
displays, go to the
“Service error codes” on page 2-3 .
User status messages provide the user with information on the current status of the printer. “Ready”
displays on the first line of the display unless Power Saver is invoked, then Power Saver is displayed. If a
user status message displays, go to the
“User attendance messages” on page 2-8 .
User error messages are indicated by a two- or three-digit error code which provides the user with
information explaining a problem with a print cartridge, paper jam, option, port, and so on. If a user error
message displays, go to the
“User attendance messages” on page 2-8 .
The User Messages section sometimes allows a servicer to isolate printer problems. This section also gives
actions to be taken when they do not set or clear.
If you have a failing symptom, go to the “Symptom tables” on page 2-11 . Locate your symptom, and take
the appropriate action.
If a service error code appears while you are working on the printer, go to the “Service error codes” on
page 2-3 and take the appropriate action.
