Detailed Self-Diagnostic Mode
In addition to the self-diagnostic test initiated every time the main machine is powered on, you can set the
machine in a more detailed diagnostic mode manually in order to test other components or conditions that
are not tested during self-diagnosis after power on.
Follow this procedure to execute detailed self-diagnosis manually.
1. Switch off the printer.
2. Press and hold down the [On line] and [#Enter] buttons together, then switch on the printer.
3. Release the buttons when you see:
DIAGNOSE
0100
4. The number will change automatically as the self-diagnostic test runs. After about 30 sec-
onds, the initial display returns and a self-diagnostic report prints.
5. A report like the one below is printed every time a detailed self-diagnostic test is executed,
whether errors were detected or not.
