Punch Section

The paper transferred from the Horizontal Transport to the Finisher passes
the Finisher Input Path Sensor in the Finisher, and it is transferred towards the
Shift Roller by the rotation of the Finisher Input Roller and Regi Roller. After
the trailing edge of the paper passed the Finisher Input Path Sensor, the
rotation speed of the Shift Roller decreases to reduce the paper transfer
speed of the Shift Roller towards the Exit Roller. Due to the reduced paper
transfer speed of the Shift Roller, a part of the paper located near the Chute
Guide starts to deflect. Paper deflection is caused by the Regi Roller rotation
faster than the Shift Roller rotation. Since then, the paper deflects
successively by the Regi Roller, and after the specified pulses, the Punch Unit
punches the paper. After the punching operation is finished, the Shift Roller
rotation speed returns to normal speed to restart the paper transfer .
