Abstract

Abstract A print job processing method and apparatus for use in an electronic reprographic system are described. Original documents of a job to be printed are scanned to provide signals for storage. The signals are transferred to a printer for print generation. An optimum time to commence printer operation is automatically determined in accordance with at least one of the number of original documents, the thickness of original documents, scanner speed, printer speed, and number of print jobs in the system. The optimum time is determined such that the maximum overlap is achieved between scanner operation and printer operation.

Claims Analysis

Total Claims: 30
Claim 1
Independent Claim 79 words
A method of processing a print job in an electronic reprographic system, comprising the steps of: scanning a set of original documents which comprise the print job; converting the scanned documents to electronic signals; storing said electronic signals for print generation; and commencing printing of the stored electronic signals during scanning of said set of original documents to minimize a time period between completion of scanning of said original documents and completion of printing of the stored electronic signals.
Claim 2
Independent Claim 79 words
A method of processing a print job in an electronic reprographic system, comprising the steps of: scanning a set of original documents which comprise the print job; converting the scanned documents to electronic signals; storing said electronic signals for print generation; and commencing printing of the stored electronic signals during scanning of said set of original documents to minimize a time period between completion of scanning of said original documents and completion of printing of the stored electronic signals.
Claim 3
Dependent Claim 43 words
The method of claim 1, further comprising the steps of: automatically determining an optimum time to commence printing of the stored electronic signals during the scanning of the set of original documents; and commencing printing of the job at the determined optimum time.
Claim 4
Dependent Claim 36 words
The method of claim 1, wherein the steps of commencing printing during scanning include the step of ensuring that a last document in said set of original documents is canned before printing of said last document.
Claim 5
Dependent Claim 38 words
The method of claim 1, wherein the step of commencing printing during scanning includes a step of ensuring that storing of a last document in said set to be scanned is completed before printing of said last document.
Claim 6
Independent Claim 84 words
An apparatus for processing a print job in an electronic reprographic system, comprising: means for scanning a set of original documents which comprise the print job; means for converting the scanned documents to electronic signals; means for storing said electronic signals for print generation; and means for commencing printing of the stored electronic signals during scanning of said set of original documents to minimize a time period between completion of scanning of said original documents and completion of printing of the stored electronic signals.
Claim 7
Independent Claim 84 words
An apparatus for processing a print job in an electronic reprographic system, comprising: means for scanning a set of original documents which comprise the print job; means for converting the scanned documents to electronic signals; means for storing said electronic signals for print generation; and means for commencing printing of the stored electronic signals during scanning of said set of original documents to minimize a time period between completion of scanning of said original documents and completion of printing of the stored electronic signals.
Claim 8
Dependent Claim 44 words
The apparatus of claim 5, further comprising means for automatically determining an optimum time to commence printing of the stored electronic signals during the scanning of the set of original documents; and means for commencing printing of the job at the determined optimum time.
Claim 9
Dependent Claim 35 words
The apparatus of claim 5, wherein the means for commencing printing during scanning includes means for ensuring that a last document in said set of original documents is scanned before printing of said last document.
Claim 10
Dependent Claim 37 words
The apparatus of claim 5, wherein the means for commencing printing during scanning includes means for ensuring that storing of a last document in said set to be scanned is completed before printing of said last document.
Claim 11
Independent Claim 84 words
A method of processing print jobs in an electronic reprographic system, comprising the steps of: scanning a set of original documents which comprise a print job; converting the scanned documents to electronic signals; storing said electronic signals for print generation; and automatically determining an optimum time to commence printing of the stored electronic signals during the scanning of the set of original documents such that scanning of said set will be completed before printing will be completed to maximize overlap of scanning and printing.
Claim 12
Independent Claim 84 words
A method of processing print jobs in an electronic reprographic system, comprising the steps of: scanning a set of original documents which comprise a print job; converting the scanned documents to electronic signals; storing said electronic signals for print generation; and automatically determining an optimum time to commence printing of the stored electronic signals during the scanning of the set of original documents such that scanning of said set will be completed before printing will be completed to maximize overlap of scanning and printing.
