Xerox WorkCentre 3335

The Phaser 3330 and WorkCentre 3335/3345 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 (dC330 Component Control). 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. On the Phaser 3330, use the arrow buttons to scroll through the menus and highlight the desired test. On the WorkCentre 3335/3345, use the TouchScreen to scroll through the menus and highlight the desired test. The Table below shows the function of the arrow buttons on the P3330. (The WC3335/45 does not have arrow keys or an OK button). The OK button runs the test.

Button	Function
Up	Moves or selects an item or parameter.
Down	Moves or selects an item or parameter.
Left	Moves the cursor to the left.
Right	Moves the cursor to the right.
OK	Confirms settings or runs the selected test.
Cancel	Resets a diagnostic item, cancel, or exit the menu.

For parameters, pressing OK after selecting an item from the menu displays the current value of the item.
