ABSTRACT:
Documents are fed to a platen of a copier from two different feeding apparatus, one of which is a recirculating feeder adapted to sequentially feed a plurality of document sheets from one document to the platen for copying each sheet in a known manner. Typically the recirculating feeder is used in making most of the copies, and it may be used to keep the machine running substantially continuously. The platen also can receive one or more sheets of another document from a document positioner. For example, the positioner can feed a document sheet that is too large to be accommodated by the recirculating feeder, or it can feed a document sheet that may not be reliably handled by the recirculating feeder (such as a document sheet made by assembling copy onto a backing sheet), or the positioner can feed documents comprising a single sheet. Also, the positioner can be used for making document masters that are then copies using the recirculating feeder. A logic and control unit for the copier temporarily interrupts a job being run from the recirculating feeder when a second job is to be run from the document positioner. After the second job is complete, the logic and control unit restarts the job in the recirculating feeder.
