2.3.5 Stack Delivery Operation
The stack is ejected each time three large size sheets*1 or five small size sheets*2 are offset on the processing tray.
The swing motor turns and the swing guide descends. This causes the upper/lower stack delivery rollers to hold the
stack. The stack delivery motor turns the stack delivery roller and return roller. At the same time, the rear end assist
guide is started by the rear end assist motor and the stack held by the stack delivery rollers is delivered in the ejection
direction. The rear end assist guide stops once it reaches the prescribed position and returns to home position when
the rear end assist motor is reversed. Then the stack delivery motor starts and ejects the stack with the upper/lower
stack delivery rollers.
*1 Varies between 2 to 4 sheets depending on the number of paper. (Example: When the number of paper is 10, stacks
are ejected in the order of 3 sheets, 3 sheets, and 4 sheets.)
*2 Varies between 2 to 6 sheets depending on the number of paper. (Example: When the number of paper is 7, stacks
are ejected in the order of 5 sheets and 2 sheets.)
