Abstract
Abstract A document copier includes a scanner adapted to convert images on hard copy pages of original documents to a series of image-characteristic electrical signals, and a writer adapted to form reproductions of original images according to received series of electrical data signals. Electronic memory receives image-characteristic signals from the scanner, stores the received image-characteristic signals for a plurality of original document pages, and applies electrical data signals according to the stored image-characteristic signals to the writer. The image-characteristic signals stored by the memory are organized into jobs according to operator instructions such that at least one subsequent job can be loaded into the memory while electrical data signals according to a prior job are being applied to the writer from the memory.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
126 words
A document copier comprising: a scanner adapted to convert images on hard copy pages of original documents to a series of image-characteristic electrical signals; a writer adapted to form reproductions of original images according to received series of electrical data signals; memory means for receiving image-characteristic signals from said scanner, storing received image-characteristic signals for a plurality of original document pages, and applying electrical data signals according to the stored image-characteristic signals to said writer; and means for organizing the image-characteristic signals stored by said memory means into jobs according to operator instructions such that at least one subsequent job can be loaded into said memory means while electrical data signals according to a prior job are being applied to said writer from said memory means.
Claim 2
Dependent Claim
126 words
A document copier comprising: a scanner adapted to convert images on hard copy pages of original documents to a series of image-characteristic electrical signals; a writer adapted to form reproductions of original images according to received series of electrical data signals; memory means for receiving image-characteristic signals from said scanner, storing received image-characteristic signals for a plurality of original document pages, and applying electrical data signals according to the stored image-characteristic signals to said writer; and means for organizing the image-characteristic signals stored by said memory means into jobs according to operator instructions such that at least one subsequent job can be loaded into said memory means while electrical data signals according to a prior job are being applied to said writer from said memory means.
Claim 3
Dependent Claim
27 words
A document copier as defined in claim 1 further comprising batching means for dividing jobs which exceed the memory means, capacity into segments to be completed separately.
Claim 4
Dependent Claim
29 words
A document copier as defined in claim 1 wherein said subsequent jobs are scanned page-by-page and loaded into said memory means as space becomes available in said memory means.
Claim 5
Dependent Claim
147 words
A document copier comprising: A) a scanner adapted to convert images on hard copy pages of original documents to a series of image-characteristic electrical signals; and B) a marking engine for producing hard copy reproductions of scanned images, said marking engine comprising: 1) a writer adapted to form reproductions of original images according to received series of electrical data signals, 2) memory means for receiving image-characteristic signals from said scanner, storing received image-characteristic signals for a plurality of original document pages, and applying electrical data signals according to the stored image-characteristic signals to said writer, and 3) means for organizing the image-characteristic signals stored by said memory means into jobs according to operator instructions such that at least one subsequent job can be loaded into said memory means while electrical data signals according to a prior job are being applied to said writer from said memory means.
