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 [1]
moves the nip movable section [2] to nip the paper by pressurizing the nip roller [4] to the
finishing tray1 paper exit roller [3] and exit the paper to the finishing tray1 direction [5].
• The tray1 paper exit sensor [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 turns ON after a specified period of time since the FNS
entrance sensor detects the trailing edge of the paper.
(2) Stapling mode
• The paper exit opening solenoid turns ON to nip the paper after a specified period of time
since the stapling operation is completed.
C. Timing to turn OFF the paper exit opening solenoid
• In all modes, the paper exit opening solenoid turns OFF after a specified period of time
since the finishing tray1 paper exit sensor detects the paper.
