Xerox WorkCentre 6605

Service Mode in the Phaser 6600 and Phaser 6600/WorkCentre 6605 printers provides service engineers with diagnostic routines for testing electromechanical components, displaying status, and accessing NVRAM. Additionally, the WorkCentre 6605 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.

Using Diagnostics

Service Diagnostics for the Phaser 6600/WorkCentre 6605 printers consist of two separate sets: the Printer diagnostics that test the print engine on both machines, and the Fax/Scanner diagnostics that test the copy, scan, and Fax functions of the WorkCentre 6605.

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.

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.

Overview of Service Mode Operation

1. Use the [▲] and [▼] buttons to select the diagnostic item to execute.
2. Press the OK button to confirm the item selected.
3. Follow the message and keep holding down the OK button until the diagnosis is started. If the diagnosis requires changing the parameter value, use the [▲] and [▼] buttons and then press the OK button

To execute the diagnosis for other items, press the Back button until the screen returns to the item to evaluate.
If an error occurs while in the diagnosis or in the middle of selecting parameter values, an error message will appear and the processing will stop.
To cancel the error message and return to the menu screen, press the Back button or the OK button.

How to Exit Service Mode

2. Press the OK button.
3. Press the OK button again, and the printer will exit Service Mode and re-start (same as the power on).
