CHAPTER 2 FINISHER UNIT BASIC OPERATION
I.
Shutter Operation
When the tray-1 passes the delivery slot, the finisher controller PCB closes the shutter mounted
on the delivery slot before moving the tray, preventing the existing stack on the tray by the delivery
slot and intrusion of the hands.
The shutter moves up (to close) when the second feed motor (M8) rotates counterclockwise,
and is held in position when the motor stops. When the second feed motor rotates counterclockwise
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 slack 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 counterclockwise to move the shutter up.
