[D] Operation of Movable Tray

The movable tray is shifted up and down by the drive from the movable tray shift motor (M12) according to the paper exit from the buffer tray or finishing tray, and the amount of the paper stack. Rotation of the movable tray shift motor is detected by the movable tray shift motor sensor (S23). Whether paper is set on the movable tray or not is detected by the movable tray paper sensor (S17).

Detecting the position of the movable tray is performed as follows.

1.Home position of the movable tray when the paper is output from the buffer tray

The movable tray is shifted up during initializing until the movable tray paper-full sensor (S16) is turned ON. After that, the tray is moved down for a specified period of time and it is stopped where the movable tray position-A sensor (S13) is turned ON. This will be the home position.

2.Home position of the movable tray when the paper is output from the finishing tray

The movable tray is shifted down from the home position when the paper is output from the buffer tray, and the tray is stopped where the movable tray position-C sensor (S15) is turned ON. This will be the home position.

3.Position of the movable tray when the paper loading capacity is 1,500 to 3,000 sheets

If the movable tray paper-full sensor (S16) is turned ON when the movable tray is in either the home position when the paper is output from the buffer tray or the home position when the paper is output from the finishing tray, it goes down to the position where the movable tray position-B sensor (S14) is turned ON. This is the position of the movable tray when the paper loading capacity is 1,500 to 3,000 sheets.

4.Position of the movable tray when the paper loading capacity is 3,000 sheets or more

When the movable tray is in the position of the paper loading capacity of 1,500 to 3,000 sheets, and the movable tray paper-full sensor (S16) is turned ON, the tray is shifted to the position where the movable tray position-A sensor (S13) is turned OFF. This is the position of the movable tray when the paper loading capacity is 3,000 or more.

Movable tray position	Movable tray position	Movable tray position	Movable tray position
	A sensor (S13)	B sensor (S14)	C sensor (S15)
(1)	ON	OFF	OFF
(2)	ON	OFF	ON
(3)	ON	ON	ON
(4)	ON	ON	OFF

*ON: The sensor signal is interrupted by the rib of the sensor rail.

OFF: The sensor signal is not interrupted by the rib of the sensor rail.
