Upper Tray Shift Up/down
The upper tray lift motor [A] moves the upper tray up/down.
Upper Position Detection
With the actuator, the limit sensor [B] detects when the tray is at its highest position (without output paper). The forced stop switch (interlock SW) [C] prevents the tray from moving up too far. When the upper tray moves up to the highest position but doesn’t stop, the forced stop switch is pushed and the tray shift motor [A] stops.
Upper Tray Full Detection
Condition 1
There are five tray full sensors [D] on the rear side of the machine. The machine uses the readings from these sensors to detect how many outputs are stacked in the tray.

Condition 2
When the feeler is pushed up as far as "1", and remains there for 13 sec., the tray is detected full. The purpose is to accurately detect “tray full” for stacks of Z-folded paper, or poorly stacked documents.
Condition 3
Shift tray detection input check: SP6123-35 is normally set to "0" (default), tray not full.
