The procedure for the factory inspection mode is as follows.
(1)
Turn the printer power switch OFF, open the top cover, and remove the drum unit.
(2)
Turn the printer power switch ON while holding down the control panel switch. The
Drum lamp comes ON.
(3)
Lightly press the panel switch again.
(4)
Check that the Drum(paper eject sensor) and Alarm(registration sensor)
lamps go OFF after all the lamps have been ON.
If the paper eject sensor is ON at this point, the Drum lamp stays ON (error).
If the registration sensor is ON at this point, the Alarm lamp stays ON (error).
(5)
Install the drum unit.
Check that the Data lamp goes OFF.
(6)
Lightly touch the registration sensor actuator.
Check that the Alarm lamp comes ON.
(7)
Close the top cover.
Check that the Ready lamp goes OFF.

Press the control panel switch.
(9)
If all the sensors are correct, the printer goes back to the Ready status. If
any error is detected, the corresponding lamp stays ON.
