Details of operation
Used to execute scanning at the speed corresponding to the set
magnification ratio.
Key operation
Changing the magnification ratio:
Fixed magnification ratio key
ZOOM UP KEY, ZOOM DOWN
KEY
Used to check MHPS (Mirror home position sensor) ON/OFF state with
the LED on the operation panel.
<Lighting when the sensor is ON>
MHPS: Paper empty LED
Used to perform SPF document transport.
The paper size is not detected. (Excluding postcards, extra large sheet
of 1m or greater.)
With SPF installed: Single transport operation
With RSPF installed: Duplex transport operation
Key operation
Changing the magnification ratio:
Fixed magnification ratio key
ZOOM UP KEY, ZOOM DOWN
KEY
Used to check sensors in SPF with the LED on the operation panel.

Used to rotate the SPF motor forward for 10 sec.
Used to rotate the SPF motor reversely for 10 sec.
Used to drive the SPF paper feed solenoid (PSOL) at the cycle of 500
msec ON and 500 msec OFF 20 times.
Used to drive the RSPF reverse solenoid (RSOL) at the cycle of 500
msec ON and 500 msec OFF 20 times.
Used to drive the RSPF paper exit gate solenoid (GSOL) at the cycle of
500 msec ON and 500 msec OFF 20 times.
Used to drive the SPF PS release solenoid at the cycle of 500 msec ON
and 500 msec OFF 20 times.
Used to check the sensors state in the shifter job separator with the
LED on the operation panel.
