High speed electronic reprographic/printing machine

Image Number 13 for United States Patent #4757348.

An electronic reprographics/printing machine with at least one scanning array for converting images on documents to image signals, a document tray for holding a stack of the documents to be scanned, a document transport to bring the documents from the tray to the array for scanning, a controller, an input device such as a keyboard, mouse, touch display, etc. for programming in programming parameters with an associated separator code, a control sheet with a bar code representation of the same separator code for interleaving with the documents for scanning by the array, a bar code discriminator for distinguishing documents with bar codes from documents without bar codes, a bar code reader for reading the bar code to identify the separator code thereon, and a control to match the separator code obtained from the control sheet with the separator code associated with the programming parameters whereby the controller operates the machine in accordance with the program parameters.
