Troubleshooting

This chapter discusses diagnostic tests, paper jams, and system messages (status and error).

Diagnostics

The printer includes diagnostic circuits and software to aid in the discovery, prevention, and correction of system problems and failures.The printer has both offline and on-line diagnostics.

Offline Diagnostics

Most of the software diagnostics are executed when the printer is powered on, and when you request diagnostic information through the control panel.

Each time the printer is powered on, it performs a power-on self test. There is no printout during this test. However, the printer displays any errors on the control panel, accompanied by an audible alarm.

You may request the following diagnostic and configuration information via the control panel, through various menus:

•Test Print: Prints various predefined graphics pages to verify that the printer can print properly on the entire page (Test Print menu).

•Print Statistics: Displays all accumulated print engine statistics, such as number of pages printed and power-on time. This is a display-only feature; there is no printout (Print Statistics menu).
