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 stati stics,
such as number of pages printed and power-on time. This is a
display-only feature; there is no printout (Print Statistics menu).
