Start
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 three-digit error code. If a
service error code displays, go to the “Service error codes” on
page 2-2.
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 “Operator
messages” on page 2-9.
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“Operator messages” on page 2-9.
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 2-25. 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 2-2 and take the
appropriate action.
