pressing both the ADVANCE and SET TOP buttons, on
the control panel, at the same time, for about five seconds
until the printer beeps and all indicators are lit. As the
self-test progresses (for about 15 seconds), the indicator
lights change. When the self-test is done, the printer
should generate a report similar to the following:
