tomatically when the switch is pressed.
Adjustment is complete if LED601 and 602 on the punch controller PCB
flashes alternately.
5) Press SW602 or 603 on the punch controller PCB to end the adjustment
mode and set all bits of SW601 to OFF.
6) Turn off the power of the host machine.

4.3.1.3 Registering the Number of Punch Holes

This operation registers which puncher unit is attached to the IC on the punch
driver PCB so that the puncher unit can be identified by the finisher. For this
reason, this operation must be performed when the punch driver PCB has
been replaced.
1) Check that the power of the host machine is off and then remove the rear
cover of the puncher.
2) Set SW601 on the punch controller PCB as shown below.
