Abstract: A sheet separating apparatus having a plurality of rollers supported along a common axis adapted to be placed upon the top sheet of a stack of paper. The rollers are adapted to be raised vertically from the stack and also their common axis support rocked so as to permit the outboard rollers to lift individually from the top sheet. Each of the rollers is provided with a one way clutch relative to its support structure.

Abstract: A transfer roller assembly having a transfer roller, is mounted adjacent a curved photoconductive surface of an electrostatographic machine so that the transfer roller is biased into contact with the surface with a minimal force sufficient only to maintain uniform contact therewith during machine operation; the roller is mounted so that it may move in a direction which is at least generally perpendicular to a tangent at the point of contact. The ratio of the radius of the photoconductive surface to that of the roller at the point of contact is not less than 3, and preferably in the range of 3 to 3.5.

Abstract: A transport mechanism for stripping a copy sheet from a photoconductive surface and transporting the copy sheet therefrom. The transport comprises a plurality of perforated belts mounted for movement relative to a vacuum plenum, a plurality of small diameter rolls being provided on the transport adjacent the photoconductive surface to support the belts at a minimal distance from the copy strip point, the detack corona emission device and the photoconductive surface.

Abstract: A biasable transfer member is herein disclosed suitable for use in transferring xerographic images from a photoconductor to a final support sheet. The member is adapted to electrically cooperate with the photoconductor to establish a directional force field therebetween capable of attracting toner from the photoconductor toward the member and features a structure which provides for a more efficient transfer operation while at the same time accurately matching the speed of the support sheet to the photoconductor.
