Abstract
Abstract A document copier, having a copier operation that includes image editing for inputting data of a production run, which data both (1) specifies special features and (2) defines areas of an original document for treatment by the special features. An interrupt mode interrupts the image editing and the image forming so that a job of higher priority can be processed. The special features specifying data and the area defining data of a production run are stored only for areas which are completely defined at the time of interrupt of the copier operation. The higher priority job is limited to a single image frame such that duplex copies and multi-color copies which require more than one image frame to produce are excluded. A job image buffer capable of holding a predetermined amount of data is provided. The interrupt operation is disabled when there is insufficient space in the job image buffer for storing the data for the higher priority job. Data for the higher priority job is erased from the job image buffer after only one copy is produced, whereby multiple copies of said high priority job cannot be produced.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
168 words
A document copier having a copier operation that includes image editing and image forming, said copier comprising: image editing means for inputting data of a production run, which data both (1) specifies special features and (2) defines areas of an original document for treatment by said special features; image forming means, operable in accordance with said image editing means, for carrying out the special features in the defined areas of a production run; interrupt means for interrupting the image editing means and the image forming means so that a job of higher priority can be processed; means, operable upon interruption of copier operation, for storing said special features specifying data and said area defining data of a production run, said storing means being operable to store said specifying and defining data only for areas which are completely defined at the time of interrupt of the copier operation; and means for resuming the copier operation for the interrupted production run after termination of the interruption by said interrupting means.
Claim 2
Dependent Claim
168 words
A document copier having a copier operation that includes image editing and image forming, said copier comprising: image editing means for inputting data of a production run, which data both (1) specifies special features and (2) defines areas of an original document for treatment by said special features; image forming means, operable in accordance with said image editing means, for carrying out the special features in the defined areas of a production run; interrupt means for interrupting the image editing means and the image forming means so that a job of higher priority can be processed; means, operable upon interruption of copier operation, for storing said special features specifying data and said area defining data of a production run, said storing means being operable to store said specifying and defining data only for areas which are completely defined at the time of interrupt of the copier operation; and means for resuming the copier operation for the interrupted production run after termination of the interruption by said interrupting means.
Claim 3
Dependent Claim
121 words
A document copier comprising: a job image buffer capable of holding a predetermined amount of data; production means operable (1) for converting images on original documents to electronic bit stream data in image frame format for input to said job image buffer and (2) for reproducing pages from image frames stored in said job image buffer; interrupt means of interrupting said production means operation so that a job of higher priority can be processed, wherein said higher priority job is limited to a single image frame such that duplex copies and multi-color copies which require more than one image frame to produce are excluded; and means for resuming operation of said production means operation upon completion of the .higher priority job.
Claim 4
Dependent Claim
121 words
A document copier comprising: a job image buffer capable of holding a predetermined amount of data; production means operable (1) for converting images on original documents to electronic bit stream data in image frame format for input to said job image buffer and (2) for reproducing pages from image frames stored in said job image buffer; interrupt means of interrupting said production means operation so that a job of higher priority can be processed, wherein said higher priority job is limited to a single image frame such that duplex copies and multi-color copies which require more than one image frame to produce are excluded; and means for resuming operation of said production means operation upon completion of the .higher priority job.
Claim 5
Dependent Claim
115 words
A document copier comprising: a job image buffer capable of holding a predetermined amount of data; production means operable (1) for converting images on original documents to electronic bit stream data in image frame format for input to said job image buffer and (2) for reproducing pages from image frames stored in said job image buffer; interrupt means of interrupting said production means operation so that a job of higher priority can be processed; means for disabling said interrupt means when there is insufficient space in said job image buffer for storing the data for said higher priority job; and means for resuming operation of said production means upon completion of the higher priority job.
Claim 6
Dependent Claim
115 words
A document copier comprising: a job image buffer capable of holding a predetermined amount of data; production means operable (1) for converting images on original documents to electronic bit stream data in image frame format for input to said job image buffer and (2) for reproducing pages from image frames stored in said job image buffer; interrupt means of interrupting said production means operation so that a job of higher priority can be processed; means for disabling said interrupt means when there is insufficient space in said job image buffer for storing the data for said higher priority job; and means for resuming operation of said production means upon completion of the higher priority job.
Claim 7
