ABSTRACT:
A control system for a collator or a combined collator-set finishing machine stops the machine in a home position in case of a sheet feeding malfunction or operation of a stop switch. A collator has a plurality of bins for storing sheets that are to be collated into sets. Sheet feeders move from a home position to engage and eject a sheet from each bin onto a conveyor for delivery to a jogger and stapler. Sensors are placed along the path of the sheets from the bins to the jogger for detecting a sheet feeding malfunction. A timing cam switch turns at a predetermined rate in timed sequence with the collating, jogging and set finishing operations. The timing cam actuates timing switches that cooperate with the sensors and with operator controlled switches to stop the machines in its home position. The stapler is also responsive to the sensors and is disabled when a sheet feeding malfunction is detected and is not enabled until the next cycle and may be operated independently of the collator.
