2.2 Feed Drive System
2.2.1 Overview
0006-6513
The puncher unit installed in the feed path between the host machine and finisher punches holes in the paper when
the paper stops temporarily. When the trailing edge of the paper reaches the prescribed position, the puncher stops
the paper to punch holes along the trailing edge of the paper.
Names and roles of the motor, solenoid, and sensors used for punching are listed below.

Constraction of the Control System
0006-6514
The puncher unit consists of a die and a punch. The punch is driven by the punch motor. The punch is attached to the
eccentric cam on the punch shaft. Rotation of the punch shaft is converted to reciprocating motion to punch holes.
The punch motor is a DC motor. The home position of the punch shaft is detected by the punch home position sensor.
To stop the punch motor, a DC motor, at the home position accurately, the punch motor clock sensor counts clock
pulses to stop the punch motor when the prescribed clock pulse count is reached. Punching is performed once by
rotating the punch shaft 180 deg from the home position. A light-receiving transistor (photosensor PCB) is provided
at the top of the paper feed path at the entrance of the puncher unit and a light-emitting LED (LED PCB) is provided
Motor Role
Punch motor Drives the punch.
Solenoid Role
Punch slide solenoid*1 Avoids a paper end.
Sensor Role
Punch motor clock sensor Detects a punch motor clock.
Punch home position sensor Detects the home position of the punch shaft.
Trailing edge sensor
(Photosensor PCB /LED PCB) Detects the trailing edge of paper.
Punch dust full sensor
(Punch dust full sensor PCB) Detects that the punch dust container is full.
