30 1 Used to check the operations of the sensors and detectors in the paper feed
section, and their related circuits.
The operations of the sensors and the detector in the paper feed section can
be monitored by the lamps on the operation panel.
(Operation/procedure)
ON/OFF of the sensors and detectors in the paper feed section can be moni-
tored with the lamps on the operation panel.

Paper exit detector (POD)
Tray open/close detector (PED1)
Manual paper feed detector (PID)
2 Used to check the operations of the sensors and detectors in the option tray
and their related circuits.
The operations of the sensors and detectors in the option tray can be moni-
tored with the display lamps on the operation panel.
(Operation/procedure)
ON/OFF of the sensors and detectors in the option tray can be monitored with
the lamps on the operation panel.
The operations of the sensors and detectors in the option tray can be moni-
tored with the lamps on the operation panel. Used to check the operations of

1 1 Used to check the operation of the scanner unit and its control circuit.
(Operation/procedure)
When the print button is pressed, scanning is performed at the speed corre-
sponding to the currently set copy magnification ratio.
The copy magnification ratio can be set arbitrarily.

and their related circuits.
(Operation/procedure)
ON/OFF of the sensors and detectors in the optical unit can be monitored with
the lamps on the operation panel.
Mirror home position sensor (MHPS)
Lens home position sensor (LHPS)
3 Used to check the operation of the lens unit and its control circuit.
(Operation/procedure)
The lens unit moves to each position of the following copy magnification ratios
continuously, and stops at each position for about 0.5 sec.
The copy magnification ratio corresponding to each stop position of the lens is
displayed on the operation panel.
