ABSTRACT:
Document sheets are fed to a platen of a copier from two feeding apparatus, one of which is a recirculating feeder adapted to sequentially feed a plurality of document sheets of one document to the platen for copying information on one or both sides of each sheet. The sheets are circulated in a manner that results in the production of collated sets of copies. The platen also can receive one or more sheets of another document fed from a document positioner. The positioner can be used to feed a document that is too large to be accommodated by the recirculating feeder, or it can feed a document that may not be reliably handled by the recirculating feeder (such as a document made by assembling pieces of 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 copied using the recirculating feeder.
