Motors
M1
Finisher Entrance Motor
Drives 1) the finisher entrance rollers, 2) and the punch waste
transport belt of the punch unit.
M2
Upper Transport Motor
Drives the paper feed rollers that feed paper 1) to the proof tray,
2) straight-through to the upper tray, 3) the pre-stack tray entrance
roller.
M3
Lower Transport Motor
Drives paper feed rollers forward and reverse in the pre-stack tray
for the switchback, and drives the other rollers in the lower trans-
port area.
M4
Upper/Proof Tray Exit
Motor
Drives 1) proof tray exit rollers, 2) extension and retraction of the
stacking sponge roller, 3) upper tray exit rollers.
M5
Feed Out Belt Motor
Drives the feed out belt that moves the stapled stacks out of the
stapling tray after stapling.
M6
Corner Stapler Movement
Motor
Moves the corner stapler horizontally on a steel rod to position
the stapler at the stapling position at 1) the front, 2) the rear
(straight stapling), 3) the rear (diagonal stapling), or 4) the front
and rear for double stapling.
M7
Paper Position Sensor
Slide Motor
Drives the movement of the paper position slide that holds the
paper position sensor (S3) that detects the position of the paper.
M8
Clamp Roller Retraction
Motor
Drives a large cam that alternately clamps and unclamps the
clamp retraction roller, the idle roller of the clamp roller pair.
When these rollers are clamped, they are part of the paper feed
path and feed the stack toward the bottom fence of the fold unit.
When the idle roller is retracted, the stacks falls a very short dis-
tance (3 mm) onto the fold unit bottom fence below. These rollers
remain unclamped while the bottom fence positions the stack for
folding and while the stack is folded by the fold rollers.
