Abstract
Abstract A method and apparatus for operating an electronic reprographic system upon detection of a fault are described. Original documents of a job to be printed are scanned to provide images for storage. When scanning is interrupted, the last captured image is stored and selectively displayed. If scanning is not completed before the interruption, the system is monitored for the occurrence of a fault before scanning is resumed. The detection of a fault occurrence requires clearance of the paper path before scanning operation can be resumed. If scanning is completed, printer operation is enabled to provide image output. Partially completed scan jobs resulting from scanner interruption are saved in operator accessible memory.

Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
111 words
A method for operating an electronic reprographic system, comprising the steps of: scanning a set of original documents which comprise a job to be printed; electronically storing in memory images of the scanned documents; converting the images to electronic pages for printing; monitoring the system for any interruption in scanning prior to completion of scanning of the job; retaining the images of successfully scanned documents in operator accessible memory upon detection of the scanning interruption to enable access to the stored images when scanning of said set has been interrupted prior to completion of the job; and displaying a last image stored in memory when the interruption in scanning is detected.
Claim 2
Independent Claim
111 words
A method for operating an electronic reprographic system, comprising the steps of: scanning a set of original documents which comprise a job to be printed; electronically storing in memory images of the scanned documents; converting the images to electronic pages for printing; monitoring the system for any interruption in scanning prior to completion of scanning of the job; retaining the images of successfully scanned documents in operator accessible memory upon detection of the scanning interruption to enable access to the stored images when scanning of said set has been interrupted prior to completion of the job; and displaying a last image stored in memory when the interruption in scanning is detected.
Claim 3
Dependent Claim
28 words
The method as recited in claim 1, further comprising the step of: permitting resumption of scanning of a document in the set immediately following the last image displayed.
Claim 4
Dependent Claim
23 words
The method of claim 1, wherein the last image stored is displayed when the scanner interruption is a result of a scanner fault.
Claim 5
Dependent Claim
26 words
The method of claim 1, wherein the last image stored is displayed depending on a scan mode in which the set of original documents is scanned.
Claim 6
Dependent Claim
24 words
The method of claim 4, wherein the scan mode is one of a platen mode, Semi-Automatic Document Handling mode or Computer forms feeder mode.
Claim 7
Dependent Claim
29 words
The method as recited in claim 1, further comprising a step of permitting resumption of scanning of a document in the set immediately following a last successfully scanned document.
Claim 8
Dependent Claim
16 words
The method of claim 1, wherein the scanner interruption is a result of a scanner fault.
Claim 9
Dependent Claim
40 words
The method as recited in claim 1, further comprising the step of: disabling operation of the system until a paper path of the reprographic system is cleared when the scanner interruption is detected prior to completion of scanning the job.
Claim 10
Dependent Claim
17 words
The method of claim 8, further comprising a step of displaying a last image stored in memory.
Claim 11
Dependent Claim
25 words
The method of claim 9, wherein the last image is displayed depending on a scan mode in which the set of original documents is scanned.
Claim 12
Dependent Claim
32 words
The method of claim 8, further comprising the step of resuming scanning of a document in a set immediately following a last document stored in memory, after clearance of the paper path.
Claim 13
Dependent Claim
32 words
The method of claim 8, further comprising a step of resuming scanning of a document on the set corresponding to a last document stored in memory, after clearance of, the paper path.
Claim 14
Independent Claim
65 words
A method for operating an electronic reprographic system comprising the steps of: scanning a set of original documents which comprise a job to be printed; electronically storing in memory images of the scanned documents; monitoring the system for any interruption in scanning prior to completion of scanning of the job; and displaying a last image stored in memory when the interruption in scanning is detected.
Claim 15
Independent Claim
65 words
A method for operating an electronic reprographic system comprising the steps of: scanning a set of original documents which comprise a job to be printed; electronically storing in memory images of the scanned documents; monitoring the system for any interruption in scanning prior to completion of scanning of the job; and displaying a last image stored in memory when the interruption in scanning is detected.
Claim 16
