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 (CL102) and shutter close detection sensor (S148) are ON, the
shutter moves up (close) when the stack ejection motor (M122) 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 (S106).
