1. In a electronic reprographics/printing machine for processing documents having images thereon, said machine having a document scanner which scans said documents to provide electrical signals representative of the images on said documents for processing by said machine, the combination of: (a) control means for controlling operation of said machine in response to control instructions; (b) a control document bearing at least one coded image providing control instructions for operating said machine to carry out a preset cycle, said control document being associated with said documents to provide at least one job batch consisting of said documents and said control document for scanning by said scanner so that said scanner when scanning said job batch outputs both electrical signals representative of the images on said documents and electrical signals representative of the coded image on said control document; (c) control document recognition means for separating the electrical signals output by said scanner from scanning said coded image on said control document from the electrical signals output by said scanner from scanning said documents; and (d) means for converting the electrical signals from scanning said coded image on said control document to said control instructions for controlling operation of said machine.
