Abstract
Printer job recovery for use in an electronic reprographic system includes the detection of faults affecting printer operation. If such a fault is detected, fault recovery is effected and operation continues. It is then determined whether the jobs are incomplete. If not, recovery is skipped and normal operation continues. If, however, it is determined that there are incomplete jobs, it is then determined whether there are any partially complete jobs. If not, normal system operation continues. Upon determination that there are partially complete jobs, the system recovers the oldest partially complete job. It is again determined whether there are any partially complete jobs. The cycle continues until it is determined that there are no partially complete jobs.
