Abstract
Abstract The handling of copy sensitive jobs in an electronic reprographic printing system comprises a unique bindexer sheet routing operation to ensure job integrity when printing copy sensitive jobs using multiset scheduling. A bindexer bin fill pattern is used which is unidirectional and begins at the same bin for each sheet of the set. Job recovery for copy sensitive jobs can include purging and remaking sets and partial sets to a greater extent for copy sensitive jobs than that required for noncopy sensitive jobs. The unique job recovery preserves the uniqueness of the copy sensitive jobs while improving the overall job recovery productivity for non-copy sensitive jobs.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
105 words
A job recovery method for use in an electronic reprographic system, comprising the steps of: scanning a plurality of sets of original documents which comprise at least one copy sensitive job to be printed; electronically storing in memory images of the scanned documents; converting the stored images to electronic pages for printing copy sets of the original documents; monitoring the system for detection of a malfunction affecting copy set handling operations in a finisher; and in response to a malfunction detection, purging only selected copy sets necessary to maintain a correct sequence of one copy set and portions of sets at a final job destination.
Claim 2
Dependent Claim
105 words
A job recovery method for use in an electronic reprographic system, comprising the steps of: scanning a plurality of sets of original documents which comprise at least one copy sensitive job to be printed; electronically storing in memory images of the scanned documents; converting the stored images to electronic pages for printing copy sets of the original documents; monitoring the system for detection of a malfunction affecting copy set handling operations in a finisher; and in response to a malfunction detection, purging only selected copy sets necessary to maintain a correct sequence of one copy set and portions of sets at a final job destination.
Claim 3
Dependent Claim
40 words
The method as recited in claim 1, wherein said step of purging includes purging one entire copy set and portions of other copy sets for a copy sensitive job and purging only affected copy pages for a non-copy sensitive job.
Claim 4
Dependent Claim
123 words
A job recovery apparatus in an electronic reprographic system comprising: scanner means for scanning a plurality of sets of original documents which comprise at least one copy sensitive job to be printed; storage means for electronically storing in memory images of the scanned documents; converter means for converting the stored images to electronic pages for printing copy sets of the original documents; monitoring means for monitoring the system for detection of a malfunction affecting copy set handling operations in a finisher; and purging means for purging copy sets in response to a malfunction detection, said purging means purging only selected copy sets necessary to maintain a correct sequence of one copy set and portions of other copy sets at a final job destination.
Claim 5
Dependent Claim
123 words
A job recovery apparatus in an electronic reprographic system comprising: scanner means for scanning a plurality of sets of original documents which comprise at least one copy sensitive job to be printed; storage means for electronically storing in memory images of the scanned documents; converter means for converting the stored images to electronic pages for printing copy sets of the original documents; monitoring means for monitoring the system for detection of a malfunction affecting copy set handling operations in a finisher; and purging means for purging copy sets in response to a malfunction detection, said purging means purging only selected copy sets necessary to maintain a correct sequence of one copy set and portions of other copy sets at a final job destination.
Claim 6
Dependent Claim
39 words
The apparatus as recited in claim 3, wherein: said purging means purges one of entire copy set and portions of other copy sets for a copy sensitive job and purging only affected copy pages for a non-copy sensitive job.
