Punch Mechanisms
Paper Position Detection
[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.
