2.5.2 Shutter Operation

When tray 1 passes the delivery section with paper already stacked, the stacked paper may get caught by the delivery
section. A shutter is provided at the delivery section to prevent this. The shutter closes when tray 1 passes the delivery
section. This is performed even when no paper is stacked.
When the shutter clutch (CL101) and stack ejection lower roller clutch (CL102) are ON, the shutter moves up (close)
when the stack ejection motor (M102) turns forward and moves down (open, delivery enabled) when the motor turns
backward.
The open/close of the shutter is detected by the shutter home position sensor (PI113).
