Abstract

A system wherein documents are presented to a platen of a xerographic system includes a housing in which a rack for storing documents is located. The rack includes a plurality of pockets in each of which a document may be stored, the rack being movable in a vertical direction so that any one of its pockets may be aligned with an opening in the housing. A document handler resting on the platen and having a fluidically lubricated platform is used to feed documents placed on the platform through the opening and into pockets of the rack. The document handler cooperates with the platen to provide a rectangular document pocket and documents in the rack may be shuttled to and from the document pocket. Fluid streams are used to initiate movement of a document being shuttled. Documents moved to the platen are orthogonally registered with a pair of walls of the document pocket, and copies of the registered documents may be made by the xerographic system.
