Paper exit roller control

The paper exit roller motor (M7) controlled by the FS control board (FSCB) drives the main tray paper exit roller
and the paper exit belt of the stacker.
A. Sort/group mode
The paper exit roller motor (M7) rotates in high speed when the FS entrance sensor (PS4) detects the leading
edge of the paper [1]. M7 rotate in low speed [2] and exits the paper a specified period of time after PS4 detects
the trailing edge of the paper.
To transfer the subsequent paper, M7 rotate in high speed again a specified period of time after the main tray
paper exit sensor (PS6) detects the trailing edge of the paper [3].
M7 stops a specified period of time after PS6 detects the last paper.

B. Stapling mode (when the paper length is B5R or longer in the paper feed direction)
Transmitting the FS operation signal [1] from the main body, the paper exit roller motor (M7) rotates to drive the
paper exit belt in the stacker section. M7 stops and the paper exit arm moves to the home position for the sta-
pling mode when the paper exit belt home sensor (PS9) turns ON [3].
The paper exit opening is open if the paper length is longer than B5R in the paper feed direction. The paper exit
motor (M8) closes the paper exit opening when the stapling operation is completed. M7 rotates to drive the
paper exit arm when the paper exit home sensor (PS12) detects the opening is closed [6]. The paper exit arm
lifts up the paper to the paper exit roller, and then the paper exit roller exits the paper to the main tray.
M7 stops when PS9 turns ON [7].
