11.1.2.2.9. Shutter Operation
When the Top Output Tray reaches capacity, the output is then switched to another tray. Using the Tray Lift
Motor (M5) the Finisher Controller PCB closes the shutter mounted on the delivery slot before moving the
tray. This prevents the existing stack on the tray from interfering with the delivery slot, and prevents any
access by hand while the trays are moving.
The shutter moves up (to close) when the Second Feed Motor (M8) rotates counter-clockwise, and is held
in position when the motor stops. When the Second Feed Motor rotates counter-clockwise once again, it
moves down (to open) to enable delivery.
When the shutter is held at the up position, claws slide out of the Swing Guide to engage the back of the
shutter. This way, the existing stack and the Swing Guide engage while the tray is moved, preventing the
guide from opening. The claws slide in when the shutter is moved down to release the engagement.
The upward movement of the shutter is monitored by the Shutter Closed Detecting Switch (MS4), and the
downward movement is monitored by the Shutter Open Sensor (PI5).
See the following diagrams for how these operations take place.
1. The Second Feed Motor rotates counter-clockwise to move the shutter up.

2. The Tray Lift Motor rotates, and the new tray moves to the stacking lower limit. The distance of
movement is detected by the Tray Shift Motor Clock Sensor 1/2 (PI9/19).
