Stack Tray Shift Operation
The paper delivered from the processing tray by the gripper is then stacked on the stack tray.
The stack tray is moved up and down by the stack tray shift motor (M8).
When the power is turned on or before start of printing, the stack tray shift motor (M8) is
driven to move the stack tray up/down to the position where the stack tray paper height
sensor (S9) detects the stack tray top surface.
After the paper has been delivered from the processing tray, the stack tray moves down by
the specified amount. Then, the stack tray moves up until the stack tray paper height sensor
(S9) detects the stack tray top surface (top surface of the stacked paper) with the stack tray
paper height sensor flag.

Stack Tray Paper Height Detection Control
The height of the paper stack on the stack tray is detected by the stack tray paper height
sensor (S9).
After paper has been delivered to the stack tray, the stack tray moves down by the specified
amount.
Next, the stack tray paper height sensor (S9) turns on (the top surface of the paper on the
stack tray is detected).
The above operations are repeated each time paper is delivered to the stack tray.
