How to Run DiagnosticsDiagnostic Tests

This section provides step-by-step instructions for running each of the diagnostic tests available through the self-diagnostic mode of the printer. Each test is referenced by num- ber. Check the contents page to find the page on which a specific test is described.

How to Run Diagnostics

Follow these steps to access the self-diagnostic mode of the printer:

1Turn off the printer and wait five seconds.

2Hold down the STOP and TEST keys simultaneously as you turn the printer back on. Continue to hold the keys down until O appears on the display. The STANDBY light flashes as the printer accesses its soft diagnostic mode, which takes approximately 1 minute. The tone, followed by 001 on the display, indicates you can now run a test.

3Change the counter to the number of the test you wish to run by pressing CANCEL to increase the counter or # TEST to decrease the counter. If you press these keys before a test is complete, a long tone sounds and the test continues without interruption.

4Press READY to run the test.

5Press STOP to end the test (in most cases; see specific diagnostic procedures for direc- tions on exiting a test).

6To exit diagnostic mode, cycle printer power.

•Most errors or conditions reported are valid for about 90 seconds, which is the timeout period set for most of the diagnostic tests described in this section.

Note

Only diagnostics useful for field maintenance are documented in this manual.
