[A]: Finisher Entrance Motor (M1) [B]: Finisher Entrance Roller
[C]: Finisher Entrance Sensor (S1)
[D]: Paper Position Sensor Slide Motor (M7) [E]: Paper Position Sensor (S27)
[F]: Paper Position Sensor Slide HP Sensor (S22)
The finisher entrance motor (M1) [A] drives the finisher entrance rollers [B] that feed paper from the copier into the finisher. The finisher entrance sensor (S1) [C] detects paper when it enters the finisher, and detects paper jams.
The paper position slide sensor motor (M7) [D] extends and retracts the paper position slide that holds the paper position sensor (S27) [E]. The paper position sensor detects the position of the paper edge. The detected position of the paper is used to calculate and position the punch unit for punching.
The paper position slide HP sensor (S22) [F] detects the paper position slide when it retracts and stops the paper position slide motor so the slide stops at its home position.

Punch Unit Movement
[A]: Punch Movement Motor (M9)
[B]: Punch Movement HP Sensor (S21) [C]: Punch Drive Motor (M24)
[A]: Punch Movement Motor (M9)
[B]: Punch Movement HP Sensor (S21) [C]: Punch Drive Motor (M24)
[A]: Punch Movement Motor (M9)
[B]: Punch Movement HP Sensor (S21) [C]: Punch Drive Motor (M24)
The punch movement motor (M9) [A] extends and retracts the punch unit to position it at the correct position for punching.
The punch movement HP sensor (S21) [B] detects the position when it retracts, switches off the punch position movement motor, and stops the punch unit at its home position.
The punch drive motor (M24) [C] fires the punches that punch holes in the paper below.

The punch drive motor (M24) [A] turns the small, notched encoder wheel [B] through the gap in the punch encoder sensor [C] (S24). The sensor output is used to control the punch timing.
The timing for 2-hole punching [E] is different from 3-hole punching [F].
When the punch unit is at the punching position, the punch motor turns until the encoder detects the starting position for 2-hole or 3-hole punching.
