11.1.3.3. Paper Output Mechanism
11.1.3.3.1. Outline
The paper output mechanism serves to keep a stack of sheets coming from the Finisher in place for the
next operation (stapling, folding). The paper inlet is equipped with the No. 1 Flapper and the No. 2 Flapper,
which operate to configure the paper path to suit the paper size. The Paper Positioning Plate is kept poised
at a predetermined location to suit the paper size. 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 moves the sheets by coming into contact with or moving away from
the sheets as needed. The Alignment Plates sets the stack in order each time a sheet is ejected. 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 ejected, 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 for a specific paper size, and the Paper Positioning Plate
is equipped with a Paper Positioning Plate Paper Sensor (PI8S).
