The stack tray is moved up and down with the stack tray shift motor (M1). 

The home position of the stack tray is where the paper surface sensor detects the upper surface of the stack tray. If the stack tray is not at the home position when

copying/printing starts, the stack tray shift motor is operated to move the stack tray to the home position. The lower limit of the stack tray is detected by the stack

tray lower limit sensor (PI10). When the stack tray lower limit sensor is turned on, the stack shift motor can run only in the direction that leaves this sensor.

1) A paper stack is ejected to the stack tray by the stack slider [1].

2) After completion of alignment, this machine operates the stack slide motor (M3) with the stack held by the Claw [2] to move the stack slider [1] toward the stack

tray, stopping the stack slide motor.

5) The lever of the paper holder is engaged with the groove in the process tray, releasing the stack.  

6) The stack stops at the raised return wall, falling into the stack tray.
