Bins - Ricoh FT4430 Service Manual

The transfer wheels have two slots in them 180 degrees apart. As the transfer
wheels turn, these slots engage the pins of the bins and lift them up. Each
time the transfer wheels turn 180 degrees, they raise one bin.
The CPU counts the bins using the wheel sensor. A cylindrical actuator on the
front transfer wheel turns the wheel sensor on and off. This actuator has two
notches that are 180 degrees apart. The wheel sensor turns on each time one
of the slots passes through the sensor.
To move the bins down, the CPU reverses the bin drive motor and the above
process reverses.
The home position sensor is located at the lower
all the bins are lowered, the lift bar presses down on the actuator, actuating
the sensor. The CPU checks the sensor whenever the power is turned on. At
this time, if the bins are not in the home position, the sensor will deactuate
and inform the CPU to return the sorter to the home position.

BINS

The
proof tray and the twenty bins are all basically the same. Formed out of
thin flexible steel plate, they have spacers on the left end to hold them apart,
and pins at the front and rear of the right end, which are inserted in guide
slots in the sorter frame.
On the right edge, the bins have stoppers [A] which prevent copies from
sliding back into the sorter after they have been fed out. The pattern of these
stoppers is different for even and odd numbered bins.
Three leaf springs [B] on the underside of each bin hold the copies flat in the
underlying bin.
