Abstract: An automatic electrostatographic duplicating machine in which computer fanfold documents are fed by an automatic handling means from a supply position above the machine platen to a second position overlaying the platen below the supply position by a tractor means having motor driven sprocket means operative to advance the document material, and control means for supplying control signals to said motor driven means to advance the document material continuously, intermittently, or to selected positions.

Abstract: A system for efficiently feeding normal sized and oversized documents into different imaging positions overlying an imaging platen. All documents are initially fed onto the platen from an infeeding position desirablefor normal documents substantially downstream from the upstream end of the platen. A normal document is only fed unidirectionally downstream into an imaging position. A sensed oversized document is initially fed downstream, but then, after its trail edge has cleared the infeeding position, it is reverse fedtowards the upstream end of the platen into a special imaging position partiallyoverlying the normally unused upstream portion of the platen. A baffle normally directly overlies that area of the platen. During the initial reverse movement of an oversized document his baffle is pivoted upwardly at its downstream edge, at the infeeding position, to provide a document guide surface under the baffle. The baffle is then lowered onto that portion of the oversized document now extending thereunder before its imaging to provide an imaging background surface, and may be raised again for downstream ejection of the oversized document. For normal documents the baffle may remain flat on the platen.

Abstract: VARIABLE EDGE FADEOUT APPARATUS FOR ELECTROSTATIC REPRODUCTION MACHINES An imaging lens system for electrostatic type reproduction machine or copiers utilizing a zoom lens effective to provide, within the magnification limits of the lens, infinitely variable image sizes. A control is provided to pre-set the lens to automatically give, upon actuation, at least one preselected image size, with an override control to enable the lens to be set to provide any image size regardless of pre-set conditions. Further controls are provided for the machine nonimage erase mechanism to automatically compensate for changes in the image borders brought about by changes in image size due to resetting of the zoom lens. For this purpose, an infinitely variable edge fadeout apparatus is provided incorporating movable shutters to vary the effective size of the edge erasure slots in correspondence with image size together with timing controls for changing the operational timing of the pitch fadeout lamp in response to changes in image size upon resetting of the zoom lens. Further controls enable the critical positioning of the image produced by the zoom lens on the photosensitive member to be adjusted to assure that the image, whatever the size, is optimally positioned on the copy produced with other controls to enable the image, whatever the size produced by the zoom lens, to be physically moved or offset on the copy.
