Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
105 words
A method of job recovery in an electronic reprographic system which prints a plurality of independent print jobs comprising the steps of: processing a plurality of independent print jobs; monitoring the system for the detection of a fault affecting printer operation; upon detection of such a fault, determining whether any of the plurality of jobs have not been completed; if determined that any of the plurality of jobs have not been completed, independently monitoring the status of all jobs; skipping recovery of any of the plurality of jobs which have been completed; and independently recovering one job per job destination for any partially completed job.
Claim 2
Independent Claim
105 words
A method of job recovery in an electronic reprographic system which prints a plurality of independent print jobs comprising the steps of: processing a plurality of independent print jobs; monitoring the system for the detection of a fault affecting printer operation; upon detection of such a fault, determining whether any of the plurality of jobs have not been completed; if determined that any of the plurality of jobs have not been completed, independently monitoring the status of all jobs; skipping recovery of any of the plurality of jobs which have been completed; and independently recovering one job per job destination for any partially completed job.
Claim 3
Dependent Claim
15 words
The method as recited in claim 1, wherein said steps are performed by a printer.
Claim 4
Independent Claim
122 words
An apparatus for job recovery in an electronic reprographic system which prints a plurality of independent print jobs comprising: processing means for processing a plurality of independent print jobs; monitoring means for monitoring the system for the detection of a fault affecting operation of the system; determining means for determining whether any of the plurality of jobs have not been completed upon detection of such a fault; independent monitoring means for monitoring the status of all jobs if determined that any of the plurality of jobs have not been completed; skipping means for skipping recovery of any of the plurality of jobs which have been completed; and recovery means for independently recovering one job per job destination for any partially completed job.
Claim 5
Independent Claim
122 words
An apparatus for job recovery in an electronic reprographic system which prints a plurality of independent print jobs comprising: processing means for processing a plurality of independent print jobs; monitoring means for monitoring the system for the detection of a fault affecting operation of the system; determining means for determining whether any of the plurality of jobs have not been completed upon detection of such a fault; independent monitoring means for monitoring the status of all jobs if determined that any of the plurality of jobs have not been completed; skipping means for skipping recovery of any of the plurality of jobs which have been completed; and recovery means for independently recovering one job per job destination for any partially completed job.
Claim 6
Dependent Claim
26 words
The apparatus as recited in claim 3, wherein: said monitoring means, determining means, independent monitoring means, skipping means and recovery means re provided in a printer.
