Paper exit roller control

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

B. Stapling mode (when the paper length is B5S or longer in the sub scan direction)
Transmitting the FNS 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 stapling 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 B5S in the sub scan 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].
