Driving the bin unit
Functional design
1
The figure below shows the drive system for the bin unit.
Output from the copier is forwarded to the bin unit by the delivery roller and
the inlet roller. These are rotated by the drive motor (M6) and the feeder motor
(M2).
The movement of the output is monitored by the delivery sensor (PI3).
The motors are DC motors, which rotate only clockwise. The drive of these
motors is controlled by pulses from the clock sensors.
