The Phaser 3320 and WorkCentre 3315/3325 printers have built-in diagnostics to test
electromechanical components, display status, and provide some NVRAM access. 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 here.
In Service Mode, menu selections are used to perform various tests to isolate the cause of a
malfunction. While in Service Mode, the machine still performs all normal operations. 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.
For parameters, pressing
OK
after selecting an item from the menu displays the current value of the
item.
