Product Technical Overview
Hole Punch Components
The hole punch assembly consists of a motor, gears, main cam, four (XE) or three (USSG,
XCL) punch cams and a punch box.
The motor raises and lowers the punches through one cycle of the gears.
When the motor rotates in a clockwise direction it operates the two inner punch cams and in a
counter-clockwise direction it operates all four (XE) or three (USSG, XCL) punch cams. Refer
to

Hole Punch Encoder
The operation of the hole punch is controlled by an encoder and sensor. The encoder has a
number of apertures cut into it and is connected to the motor. As the motor rotates the gears to
operate the hole punch, the encoder also rotates.
The rotation of the encoder is monitored by the encoder sensor which is an optical sensor that
reflects light onto the encoder. Refer to
Figure 46
.
Figure 46 Hole punch encoder
The rotation of the encoder wheel causes the apertures to pass through the encoder sensor
wheel, allowing light to pass. This triggers the sensor, which indicates that the hole punch has
rotated one cycle. Refer to
