Process output bin paper-stacking operation
When the trailing edge of the paper exits the first delivery roller, the sheet is delivered to the
processing output bin by the stack-delivery roller and return roller and then pushed against the
processing output-bin stopper.

Shutter operation
To prevent the delivery section from catching stacked paper in output-bin 1 when it passes, a shutter
is provided at the delivery section. The shutter closes when output-bin 1 passes, even when no paper
is stacked. When the shutter clutch (CL101) and stack-ejection lower-roller clutch (CL102) are on, the
shutter moves up (closes) when the stack-ejection motor (M102) turns forward and moves down
(open, delivery enabled), which occurs when the motor turns backward. The shutter home-position
sensor (PI113) detects the opening and closing of the shutter.
