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 (CL31) and stack-ejection lower-roller clutch (CL32) 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.
