Feed Drive System
Overview
The machine punches holes in paper when the paper has been stacked in the finisher and
stopped.
When paper arrives from the host machine, the shift roller starts to move it ahead; the shift
transport motor then moves the paper back to the puncher unit and forces its trail edge
against the stopper to remove the skew to prepare for punching operation.
The chips occurring as the result of punching are collected in the punch chip case, which is
monitored by a reflection type sensor for identification of a full state.
The following shows the motors and sensors used for punching operation:
Motor Description
Punch motor (M24) Drives the Rack slider
Sensor Description
Punch 2/3hole sensor (PS39) Detects the Rack 2/3hole position of the
slider
Punch clock sensor (PS38) Monitors the speed of punch motor rotation
and timing at which the slider movement is
stopped
Punch motor home position sensor (PS36) Detects the Rack position
Punch front sensor (PS37) Detects the slider front/rear position
Punch chip case sensor (PS40) Detects the presence/absence of the punch
chip case
Punch chip case full sensor Monitors the state (full) of the punch chip
