12.3 Paper collection system

12.3.1 Overview

The paper collection system collects the paper from the finisher in the paper path, in
preparation for stapling and folding in the next process.
Paper inlet flappers 1 and 2 switch the route in which the paper is sent according to size.
The paper positioning plate waits at a position determined in advance according to the size
of the paper. The paper positioning plate is driven by the paper positioning plate motor
(M44) and its position is detected by the number of motor pulses from the paper positioning
plate home position sensor (PI49). The paper sent by the inlet rollers is collected in the
specified position by the feed rollers and crescent roller. The feed rollers contact and release
according to the collection and feeding status.
Each time a sheet of paper is collected, it is aligned by the jogging plate. The jogging
plate is driven by the jogging motor (M45), and the position of the plate is detected by the
number of motor pulses from the jogging plate home position sensor (PI54).
The guide plate covers the folding rollers, preventing interference with the paper during
collection. The guide plate is lowered and does not cover the rollers during the folding.
The paper is detected according to size by the paper sensors 1, 2 and 3 (PI1A, PI2A,
PI3A) in the inlet area, and the paper positioning plate paper sensor (PI68) in the paper posi-
tioning plate area.
