Paper exit opening solenoid control

The paper exit roller is usually releasing the nip except when exiting the paper because its rotation is slower than
the transfer roller. However, the nip movable section moves to nip the paper when the paper reaches to the
paper exit opening.
A. Paper exit opening solenoid operation
When the paper reaches to the paper exit opening, the paper exit opening solenoid (SD4) [1] moves the nip
movable section [2] to nip the paper by pressurizing the nip roller [4] to the main tray paper exit roller [3] and exit
the paper to the main tray direction [5].
The main tray paper exit sensor (PS6) [6] detects the paper exit.

B. Timing to turn ON the paper exit opening solenoid
(1) Non-sort/sort/group mode
The paper exit opening solenoid (SD4) turns ON after a specified period of time since the FNS entrance sensor
(PS4) detects the trailing edge of the paper.
(2) Stapling mode
The paper exit opening solenoid (SD4) turns ON to nip the paper after a specified period of time since the sta-
pling operation is completed.
C. Timing to turn OFF the paper exit opening solenoid
In all modes, the paper exit opening solenoid (SD4) turns OFF after a specified period of time since the main tray
paper exit sensor (PS6) detects the paper.
