1.2.1 Adjusting the Punch Hole Position
This mode requires operation in service mode. The range of hole displacement is between 3
and -3 in 1-mm increments. A higher setting will move the hole toward the leading edge of
sheet. (See the Service Manual of the host machine.)
1.2.2 Adjusting the Sensor Output
Perform the following when the punch controller PCB, horizontal registration sensor
(photosensor PCB/LED PCB), or waste full sensor (waste full photosensor PCB/waste full
LED PCB) has been replaced.
1) Shift bits 1 through 4 on the punch controller PCB as follows:
F05-102-01
2) Press SW1002 or SW1003 on the punch controller PCB. A press will automatically adjust
the sensor output.
• The adjustment is over when all LEDs on the punch controller PCB are ON: LED1001,
LED1002, LED1003.
3) Shift all bits of DIPSW1001 to OFF.
