Abstract: A document control and audit apparatus to monitor, control and audit documents printed by a non-impact printer for detecting missing pages, duplicate pages, and double or multiple pages. The document control and audit apparatus ensures that the proper number and sequence of pages or forms are included in a printed report or document and maintains detailed information of the contents of the individual documents, thereby providing a real time record or account and final record of the activities which occurred during the printing process. The document control and audit apparatus includes a video camera and a number of optical sensors for sensing the location and position of the pages as the pages pass through the document control and audit apparatus.

Abstract: A matching system for use with an inserting device adapted to insert into an envelope, which may be personalized for a particular recipient, one or more personalized inserts. The matching system ensures the proper assembly of mass mail items which include personalized components, each having an alpha-numeric sequence indicator printed thereon which corresponds to a given recipient. The matching system includes a number of video cameras, each positioned to sense an alpha-numeric sequence indicator on a different component of a mail item being assembled. The video camera create electrical signals in accordance with the sensed indicators which are processed by circuitry to develop and store digital representations of the sensed indicators. A controller, consisting of a master processing unit and a number of slave processing units, receives the stored digital representations and determines from them whether the sequence indicators on the personalized components to be assembled into a mass mail item match.
