Punching
After punching positions are determined, the punch unit motor is activated to move the cam plate. With the
movement of the cam plate, the pins descend along the guide holes to punch the media.
This operation is performed for each sheet of media.
The cam plate can lower the pins even while it is moving to the front or rear side.
The punch unit motor is rotated forward or reversely for each sheet of media, which is triggered by the sensor
(punch cam front) on/off.
