General Troubleshooting
Service Diagnostics
The Phaser 6500 and WorkCentre 6505 printers have built-in diagnostics to test
electromechanical components, display status, and provide some NVRAM access.
Additionally, the WorkCentre 6505 MFP has diagnostic tests for the Fax and
Scanner subsystems. Use these tests to diagnose problems and isolate which
component or sub assembly part needs replacement.
If you are confronted with an error that requires more than a cursory investigation
to clear, or when you are directed by a troubleshooting procedure, use the
diagnostic tests to exercise selected sub-assemblies or parts in the vicinity of the
reported error. Diagnostic tests are controlled from the Control Panel and are
described in detail in “Printer Diagnostic Test Descriptions” on page 4-12.
Using Service Diagnostics
Service Diagnostics for the Phaser 6500 and WorkCentre 6505 printers consist of
two separate sets: the Printer diagnostics that test the print engine, and the Fax/
Scanner diagnostics that test the copy, scan, and Fax functions of the MFP.
Most diagnostic tests are straightforward and require no additional explanation,
but there are some that require specific conditions be met to achieve meaningful
results. These instructions cover each of the test groups, listing special instructions,
conditions, or other information necessary to successfully interpret the results of
the diagnostic tests.
Diagnostic tests are arranged in a menu structure. Use the arrow buttons to scroll
through the menus and highlight the desired test. The
OK button runs the test.
During the test, the Ready and Error LEDs are turned On. Press Cancel to stop the
test. To switch between test groups, exit the current diagnostics mode and return
to the Service Mode menu.
Note
To switch between Printer Diag mode and Fax/Scanner Diag mode, you must
exit Service Mode and restart it to select the other mode.
