3. BIN DRIVE MECHANISM

The bin drive mechanism moves the bins up and down to receive copies under the direction of
the copier CPU. The main components in this mechanism are the bin drive motor [A], the
helical wheels [B], the bin sensor, and the bins [C] themselves. Pins on either side of each bin
fit into the slots of the bin holder [D]. The pins slide up and down in these slots.
A timing belt turns both helical wheels. The rear pulley has a slot which detects when the
helical wheel has rotated 360 degrees. The helical wheels Iift and lower the bins. They also lift
the bin holder itself by lifting up the bottom bin.
The roller drive motor [E] drives the exit rollers [F] and the transport rollers [G]. When the
copy activates the copier's exit sensor, the CPU sends a signal to the sorter to turn on the
roller drive motor. It turns off shortly after the sorter's paper exit sensor is deactivated.
