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
