Stapling - Xerox Paser 7400 Service Manual

Stapling

After stacking and alignment of paper on the processing tray is complete, the finisher
controller board moves the stapler for stapling according to the specified stapling
position. When the controller specifies rear 1-point stapling, the stapler does not
move; it staples while in the standby position. If a different stapling option is selected,
the stapler moves forward and the processing tray stopper leans to the forward
position.
The Finisher Slide Motor moves the stapler unit. The Slide Home Position Sensor
detects when the unit reaches its home position. The stapler waits at the back end of
the stack irrespective of the staple mode and paper size.

The position of the stapler depends on the staple mode:
Front 1-point stapling - The stapler moves to the front stapling position of the
paper for stapling and then returns to the standby position.
Rear 1-point stapling - The stapler moves to the opposite end (rear) of it's travel
length for stapling and then returns to the standby position.
Middle 2-point stapling - The stapler moves to the rear stapling position first,
then to the front stapling position, and then returns to the standby position.
The Staple Empty Sensor detects the presence of a staple cartridge in the machine as
well as the presence of staples in the cartridge. A Staple Top Position Sensor
determines when to push staples up to the top of the staple cartridge.
