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.

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 a service error code appears while you are working on the printer, go to the “Service error codes” on page 2-2and take the appropriate action.
