  • Patent number: 5513017
    Abstract: An automatic document imaging mode selection system in a system for generating electronic images of documents, in which documents may be variously fed or registered on a document imaging platen with a plural mode automatic document handling system. Various document handling and/or image scanning modes of operation are automatically selected from among various available potential such modes by accessing various document handling status information and/or sensor inputs, and coordinating that information to automatically select an optimum such mode where the operator has not specifically selected a mode. This may further include automatically determining whether or not to conduct a special pre-scan cycle before image scanning is initiated, and/or taking into consideration inferences as to whether or not the document(s) had been previously imaged. It may further or additionally include automatically changing the registration or scanning position for the particular document in accordance with the mode selection.

  • Patent number: 5212566
    Abstract: An electronic reprographic system with a scanner for scanning the document pages of a job and converting the document images scanned to pixels, a printer for making prints of the documents from the pixels in accordance with job programming instructions, a controller section with memory for use by both the scanner and the printer simultaneously, the scanner and printer operating asynchronously with respect to one another, the ability to abort scanning of a document when either the scanner or printer runs out of allocated system memory during operation, the system memory getting reallocated in preparation of a new scan, and the document that was not completely scanned getting rescanned.

  • Patent number: 5119206
    Abstract: An electronic printing system for printing bound documents such as books in which the pages of the document are placed face down in registered position on the platen of a scanner programmed to scan either or both sides of the page and provide image signals representative of the image scanned, and a printer programmable to either print both sides of a page on a common print media sheet or on separate print media sheets.

  • Patent number: 5057869
    Abstract: An electronic printing system for scanning signature pages for signature jobs in which the pages of the document are placed face down in registered position on the platen of a scanner such that the signature images are side by side in the fast scan direction in order to enable an array to view both images concurrently on relative movement between the array and the platen in a slow scan direction.
