6. Punch module (MX-PNX2A/B/C/D)
A. Basic operations
(1) Outline
The punch module is an option, and is designed for installation
between the host machine and the paper path of the finisher.
When the sheets from the host machine reach the punch module,
they are fed by the punch feed roller. When the trailing edge of a
sheet from the host machine reaches the punch module, the sheet
is stopped once, and the punch shaft is rotated to punch a hole
along the trailing edge. These operations are controlled by the fin-
isher control PCB, and the components of the punch module are
driven by the punch controller PCB.

B. Punching operation
(1) Outline
The punch module is located in the paper path from the host
machine to the finisher, and is used to punch holes in sheets when-
ever they are stopped once. The sheets from the host machine are
led by the punch feed roller. When the trailing edge of a sheet
reaches the punch module, the punch feed roller stops the sheet
once to punch a hole along the trailing edge of the sheet.
Names and functions of the motors and sensors to be used for
punch operation are shown below.

(2) Control configuration
The punch module has a die and hole puncher (punch blade). The
hole puncher is driven by the punch motor (FPNM). It is attached to
the eccentric cam of the punch shaft, and rotation of the punch
shaft is converted into reciprocating motion for punching operation.
The punch motor (FPNM) is a DC motor. The home position of the
punch shaft is detected by the punch home position sensor
(FPHPD). To make sure that the punch motor (FPNM), which is a
DC motor, stops exactly at its home position, the punch motor is
stopped in relation to the count of the clock pulses kept by the
punch motor clock sensor (FPE). A single punching operation is
executed by rotating the punch shaft 180

DC motor, stops exactly at its home position, the punch motor is
stopped in relation to the count of the clock pulses kept by the
punch motor clock sensor (FPE). A single punching operation is
executed by rotating the punch shaft 180
° from its home position.
As many as five light-receiving transistors (photosensor PCB) are
mounted over the inlet paper path of the punch module; on the
other hand, as many as five LEDs (LED PCB) are mounted under
the path, together serving as five sensors. The frontmost sensor
(LED5, PTR5) is used as a trailing edge sensor to detect the train-
ing edge of sheets, and the remaining four (LED1 through LED4,
PTR1 through PTR4) are used as horizontal registration sensors to
detect the rear position of sheets when punching holes.
The punch motor, punch module, and sensors shown above make
up the punch slide unit, which moves to the front/rear to suit the
selected paper size. The movement to the front/rear is driven by
the punch horizontal registration motor (FPSM). The home position
of the punch slide unit is detected by the horizontal registration
home position sensor (FPSHPD), and the horizontal registration
motor (FPSM) is a two-phase stepping motor.
The punch motor and the horizontal registration motor are driven
by the punch controller PCB according to the control commands
from the finisher controller.
The waste paper occurring as the result of punching is collected in
the waste paper case. The case is monitored by the reflection type
sensor (FPDD on the dust full sensor PCB).
