- Shift Tray
In shift mode, when the last printed paper has been output, the shift motor moves the shift tray to the left or the right. When one of the half-turn sensors detects one of the slots in the shift gear disk, the motor stops. The shift amount is 15mm..
- Up / Down
The shift tray moves up or down depending on the stack height of the output paper. The degree of motion is adjusted to keep the paper height sensor actuator (3) between the two paper height sensors (1, 2).

- Shift Up
When paper is removed from the shift tray, the feeler moves down and the paper height sensor (staple mode) turns ON. Then the shift tray lifts until the sensor turns “OFF”. - Shift Down (Shift Mode)
With stacked paper on the tray, the paper height sensor (standby mode) is turned “OFF”. Then the shift tray lift motor turns “ON” to lift the tray until the sensor turns “ON”. - Shift Down (Staple Mode)
When a stapled stack of paper has been output, the shift tray lift motor turns ON for a certain time to move the tray down a set distance. Then the motor lifts the tray until the paper height sensor (staple mode) turns from “ON” to “OFF”. The tray is now at the home position. This is done every time after a stapled stack of paper is output. There are three shift tray full sensors, but only two of these (4, 5 in the above diagram) are used for the machine display.
Rough Indication:
Larger Size (B4 or larger): 1,500 sheets
Smaller Size (less than B4): 3000 sheets - Drag Roller Operation
The drag roller mechanism improves the accuracy of paper stacking on the tray by pushing the output paper back against the end fence. The drag roller motor drives the roller.
