Upper Tray Raising and Lowering
Operation Mode
Sensors, Switch Action
[C] [D] [F] [G]
Standby (Non-Sta-
ple Mode)
OFF OFF
Stops the lift motor is at the standby position when
the actuator of the upper feeler deactivates sen-
sor [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.
Straight Through ON 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].
Shift ON
Standby
(Staple Mode)
ON
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 dis-
tance immediately after the stack exits.
• The upper tray rises until the actuator acti-
vates 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 back-
up if sensor [C] fails.
Tray Full
B804
When the actuator on the tray activates the upper tray full sensor [H] the tray lift motor [A]
switches off. Operation resumes after some copies are removed from the tray. Upper Tray
Capacity: 2,000 sheets (A4, LT)
B805
The operation of the upper tray full sensor is the same as the B804. Capacity: 1,500 sheets for
A3, B4 or other large paper.
An additional upper tray full sensor (below sensor [H]) allows more sheets to stack on the upper
tray. Capacity: 3,000 sheets (A4, LT)
