Stops the lift motor is at the standby position when the actuator of the upper feeler deactivates sensor [C] (when it is between sensors [C] and [D]).

Note: Sensor [F] and switch [G] are used as backup if sensor [C] fails or if the upper tray is not attached.

Non-staple mode operation: During operation, tray lift is controlled only by sensor [F]. When the actuator leaves sensor [F], the tray lowers until the actuator reactivates sensor [F].

Standby: The upper tray stops and waits for the paper output when the actuator activates sensor [C]. [D] is not used for staple mode

Staple Mode Operation:

 The upper tray lowers the prescribed distance immediately after the stack exits.

 The upper tray rises until the actuator activates sensor [C] and stops the tray lift motor (and the tray) to wait for the next set.

 Sensor [F] and switch [G] are used as backup if sensor [C] fails.
