Five sensors and one switch control the operation of the upper tray lift motor [A].
Upper Tray Raising and Lowering
Sensors, Switch Action Operation Mode
[C] [D] [F] [G]
Standby
(Non-Staple Mode) OFF OFF 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.
Straight Through ON
Shift 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].
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
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.
Tray Full
B700 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)
B701 The operation of the upper tray full sensor is the same as the B700. 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)
