[A]: Finisher Entrance Motor (M1)

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.
