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.
• This is the ‘1’ position in the diagrams (the top diagram is for 2-hole punching, and the bottom diagram
is for 3-hole punching).
Then, the punch drive motor turns counter-clockwise to the ‘2’ position. This movement punches the holes
in the paper.
Then, the punch drive motor turns clockwise to the ‘1’ position, to be ready for the next sheet of paper.
Punch Hopper Mechanism
[A]: Finisher Entrance Motor (M1)
[B]: Punch Waste Belt
[C]: Punch Waste Hopper
[D]: Punch Hopper Full Sensor (S4)
The finisher entrance motor (M1) [A] drives the timing belt and gears that rotate the punch waste belt [B].
The punchouts fall from the punch unit onto the belt. The belt moves the punchouts to the front and dumps
them in the punch waste hopper [C].
The punch hopper full sensor [D]:
• Signals that the hopper is full when it detects the top of the stack of punchouts that have collected in
the hopper.
