Mechanism
The punch unit is in the finisher paper feed unit, and when paper transported from the main machine
stops, it makes two punch holes in the rear edge of the paper one sheet at a time.
Offset in the angle of the paper is corrected by skew correction, and offset in the lateral direction is
corrected by moving the punch unit.

2.
The Entrance Sensor (S18) [A] detects the paper.
3.
The paper is brought into contact with the entrance roller [B].
4.
Skew correction is applied to the paper, and it is transported.
Registration
1.
The Horizontal Registration Correction Sensor (S29) [A] detects the lateral offset of the paper.
2.
The punch unit moves by the lateral offset detection amount, and completes punching.
