3-2 Phaser 7750 Printer Service Manual
Introduction
This section covers troubleshooting procedures for the Phaser 7750 printer front panel
error messages and codes. Only jams and fatal errors will produce an associated
numeric code. Error messages and codes are generally specific, making it important
that service personnel and users record errors when reporting problems with the
printer. Any code associated with an error message or jam can be viewed by pressing
the INFO button and scrolling to the bottom of the help text displayed on the front
panel.
Some procedures require performing service diagnostic tests to verify a specific
printer part is operating correctly. For information on Service Diagnostics and all
internal printer test functions, refer to "Service Diagnostics" on page 4-2.
To troubleshoot problems not associated with a front panel message or code, see
"General Troubleshooting" on page 4-1.
When an error first occurs, record the error message and code then cycle power to the
printer to see if the error recurs.
Always follow the safety measures detailed in the front of the manual when servicing
the printer, see “Service Safety Summary” on page vii.
