•
The Fin Input Path Sensor monitors paper being transferred from the H-Tra into the
Finisher.
•
At the specified pulses after this sensor detects the trailing edge of the paper, the
Shift Roller rotation speed decreases to start the punching operation.
•
The Fin Path Sensor monitors the paper passing condition between the Fin Input
Roller and the Regi Roller.
•
The Punch Unit punches paper.
