The paper output mechanism serves to keep a stack of sheets coming from the finisher in place

for the next steps (stapling, folding).

The paper inlet is equipped with the No.1 flapper and the No.2 flapper, which operate to config-

ure the paper path to suit the size of paper. The paper positioning plate is kept in wait at a predeter-
mined location to suit the size of paper. The paper positioning plate is driven by the paper positioning
plate motor (M4S), and the position of the plate is identified in reference to the number of motor
pulses coming from the paper positioning plate home position sensor (PI7S). A sheet moved by the
inlet roller is handled by the feed rollers and the crescent roller and held in a predetermined position.
The feed plate serve to move sheets by coming into contact with or moving away from sheets as
needed.

The alignment plates put the stack into order each time a sheet is output. The alignment plates are

driven by the alignment motor (M5S), whose position is identified in reference to the number of
motor pulses coming from the alignment plate home position sensor (PI5S).

To prevent interference between paper and the paper folding rollers when the paper is being

output, the folding rollers are designed to be covered by a guide plate. The guide plate moves down
before paper is folded so as to expose the paper folding rollers.

The inlet is equipped with the No.1, No.2 and No.3 paper sensors (PI18S, PI19S, PI20S) each

suited to a specific paper size, and the paper positioning plate is equipped with a paper positioning
plate paper sensor (PI8S).
