Abstract: A multi-function document processor, including proof inscribing and sorting functions. The document feed station keyboard, and stacker are connected in such a fashion so as to allow easy access to each of these machine elements by an operator without leaving a seated position. The advantageously accessible arrangement of functional elements is achieved by a novel use of rotary document processing stations, resulting in a folded transport path of significantly shorter length, and a transition station for moving the documents from a first plane into a second plane for more compact stacker pocket orientation. Document travel through the improved transport and into the stacker pockets is controlled by logic in the form of a plurality of microprocessors communicating via an okay to send wire.
