After the Horizontal Registration Correction Sensor (S29) detects the paper rear edge (as viewed from
the front of the machine), the machine compares it with the paper size set in the MFP. The Horizontal
Registration Correction Motor (STM15) is then driven to a predetermined position at the front, and stops
the punch unit.
Punch Unit Movement
The punch unit moves towards the front or the rear according to the paper size. The front-rear
movement is driven by the Punch Unit Moving Motor (STM14) [A]. The home position of the punch unit
is detected by the Punch Unit HP Sensor (S30) [B].
Punch Drive
Punching is driven by the Punch Drive Motor (DCM8) [A]. The punch home position is detected by the
Punch HP Sensor (S33) [B].
Punch Drive Motor (DCM8) rotation control feeds back the encoder wheel rotation speed detected by
the Punch Pulse Wave Count Sensor (S34) [C] to the Punch Drive Motor (DCM8).
Punching is performed by moving the punch unit once back and forth, by rotating the punch shaft 180
degrees from the home position.
