Phaser 4500/4510 Service Manual 3-21
Error Messages and Codes
Troubleshooting Procedures for Error Messages and Codes
The Error Message Summary tables that follow are the lead-ins to the
procedures that follow in subsequent pages. There are two tables because
the Engine Error and Jam Error codes are not the same for both printers. The
Control Panel Message column lists the error message that appears on the
control panel when the error occurs during normal operation. The Diagnostic
Message column lists the error message that appears when the error occurs
during use of Service Diagnostics. The Engine Errors column lists the code
number that appears in fault histories, either on the control panel display
when you view Engine Error History or in the Service Usage Profile at line
262 Engine Error Log. The Jam Errors column lists the code that appears on
the control panel display when you view Jam History for the Phaser 4500 or
the Printer Status page for the Phaser 4510. The Procedure to Use column
lists the page number of the troubleshooting procedure for that error.
For the Phaser 4510 printer, refer to the “Service Code Table” on page A-6,
which maps the engine error and jam error codes to specific error messages.
The procedures that follow the table are named with the messages that
appear on the control panel when an error occurs. The error codes listed in
the procedure are the fault codes displayed in Service Diagnostics along with
the fault condition that produced the code.
