Shutter Control - Canon SADDLE FINISHER K3 Service Manual

CHAPTER 2 OPERATION OVERVIEW

6.1.4 Shutter control

When there is paper stacked in tray A as it passes through the delivery assembly, the
stacked paper may enter the delivery assembly. In order to prevent this, the delivery assem-
bly is fitted with a shutter. The shutter closes when tray A passes through the delivery as-
sembly. This action takes place even if there is no paper in the tray.
The shutter is driven by the paddle motor (M9). When the paddle motor rotates forward,
it drives the paddle. When it rotates in reverse, it drives the shutter. The shutter open/close
status is detected by the home position sensor (PI12).
