Job Interrupt After Copier Jams

This article relates to a job recovery procedure for a copier machine where job 1 has been interrupted by job-2 but a paper jam occurs before job 2 can commence operation.

When a jam occurs after a job interrupt request has been made, one possible procedure would be to clear the jam, proceed with the interrupt, run the interrupting job, and resume the original job at the beginning of job recovery. However, this approach is logically complicated since recovery information must be retained through the interrupting job and could be confusing to the operator when a "Recopy Last Originals" message appears when job 1 is restored. Such a message could be misinterpreted as a prompt for job 2.

To avoid these problems, the job interrupt procedure described herein will allow interrupts only after job recovery has been started. Furthermore, a counter is implemented to remember the number of originals which have been requested for recopying but have not been fed yet. As long as this counter is not zero, originals may be fed into the copier, overriding the interrupt request. When all requested recopies have been made, however, no further original entries will be allowed until the interrupt state change has occurred.

If an operator has been requested by the job recovery logic to recopy more than one original but does not enter the second original before the copier stops running, a state change will be allowed.
