2) When the Horizontal Registration Sensor (LED1 though 4, PT1 through) suited to the paper size
signal from the Host Machine detects the rear edge of the sheet, the Horizontal Registration Motor
(M2P) causes a farther move to a specific position, and stops the Punch Slide Unit.
3) When the Trailing Edge Sensor (LED5, PT5) detects the trailing edge of the sheet, the drive of the
Feed Motor (M2) is stopped, thereby stopping the sheet. Then, the Punch Motor (M1P) is driven to
punch holes in the sheet.
4) When the punching operation ends, the Feed Motor (M2) of the Fisher Unit is driven and, at the
same time, the Horizontal Registration Motor (M2P) is rotated in reverse to return the Punch Slide
Unit to its home position.
5) For each sheet that arrives in succession, the Punch Slide Unit is returned to its home position, and
is caused to repeat steps 1 through 4.
