Booklet Finisher SR3220 / Finisher SR3210 (D3B9/D3B8)
Ascent
The shift tray paper surface sensor detects the movement upper limit of the shift tray, and disconnects the control circuit of the tray lift motor.
When paper is removed from the shift tray and the shift tray paper surface sensor switches ON (unblocked), the shift tray ascends, and when the sensor switches OFF (blocked), it stops.
Descent
In shift mode
When every 5 sheets of paper are delivered to the shift tray, the tray moves up and down. The shift tray first descends until the shift tray paper surface sensor switches ON (unblocked), and the shift tray then ascends until the sensor switches OFF (blocked).
In stapling mode
When exiting the paper to the shift tray, the tray lift motor switches ON/OFF for a definite time, and the tray height is adjusted.
Shift tray full detection
Small size (Smaller than A4 SEF, LT LEF)
When the shift tray descends and the actuator [A] under the shift tray switches the lower limit sensor (lower) [B] OFF (blocked), shift tray "Full" is detected.
Large size (Larger than B4, LG)
When the shift tray descends and the actuator [A] under the shift tray switches the lower limit sensor (upper) [C] OFF (blocked), shift tray "Full" is detected.
