Error Messages and Codes
Introduction
This section covers troubleshooting procedures for the Phaser 4400 Laser Printer’s
front panel error messages. Only jams and fatal errors will produce an associated
numeric code. Error messages and codes are usually specific, making it important that
service personnel and users record errors exactly when reporting problems with the
printer.
Any error code associated with an error message or jam can be viewed by pressing the
INFO
key. Jam error are displayed at the beginning of the info menu, while engine
errors are display at the end.
Some procedures require running Service Diagnostics tests to verify a specific printer
assembly is operating correctly. Refer to
Service Diagnostics
on page 2-7.
To troubleshoot problems not associated with a front panel error message or code
such as ac power, or problems related to print-quality, refer to the section
Troubleshooting
on page 3-1.
