The sorter has two sensors which are used to detect misfeeds in the sorter. Also, the exit
sensor in the copier is used to check for misfeeds in the sorter. The two sorter sensors each
have two misfeed check timers. After each misfeed check timer is set (starts), misfeed check
is continuous for the timer period. The timer must be reset within the timer period by the
appropriate sensor going either ON or OFF as shown in the following table. If the timer is not
reset within the timer period, the sorter CPU determines that there has been a misfeed and it
energizes the interrupt solenoid to allow the remaining copies to go to the interrupt pin.
