A method for producing a replaceable fuser member including a thin, seamless or welded high temperature nickel sleeve, a base cushion positioned around the sleeve and an outside topcoat applied over the base cushion elastomer layer. The sleeve is replaceable on a machine mandrel positioned in an electrophotographic copying machine in a fuser section of the electrophotographic copying machine. The method includes the use of a mandrel having a coefficient of thermal expansion similar to that of the sleeve to support the sleeve during positioning of a cured base cushion layer around the sleeve and a cured topcoat layer over the cured base material.

This invention relates to a method for testing a plastic sleeve for use with an image cylinder or a blanket cylinder in an electrophotographic process.

Method for testing a plastic sleeve for an image cylinder or a blanket cylinder

An improved method for producing a metallic core for use in the production of a blanket cylinder or an image cylinder sleeve for use in electrophotographic processes. The sleeves includes aluminum or other suitable metal, which is rendered more suitable for use as a sleeve surface by oxidation.

A method for producing a substrate for a photoconductive member includes etching the substrate with a self-limiting acid that removes the metal oxides from but does not affect the surface roughness of the substrate inner and outer surface.

Photoconductive member for an electrophotographic machine and method of forming same

A photoconductive member for use in an electrophotographic machine includes a substrate having an inside and outside surface. An inner smoothing layer is disposed over the inside surface of the substrate thereby improving the compatibility of the photoconductive member with an air-mounting process by which the photoconductive member is operably associated with a mandrel.

A double-sleeved roller (DSR) including: a mandrel having a disconnectable end incorporating three termination plates having specified axial profiles; a replaceable inner sleeve member (ISM) mounted on the mandrel; and, a replaceable multilayer outer sleeve member (OSM) including at least one synthetic layer with the OSM surrounding the ISM. The mandrel, adapted to support a non-reinforced ISM, includes the termination plates joined together so as to define two sets of channels for selectively conveying pressurized air to either OSM or ISM for radial expansion thereof. The termination plates have specialized outer shapes, with each termination end plate including a cylindrical portion adjoining a tapered portion. For removal and/or replacement of the OSM or the ISM, a removable support member is moved away from the disconnectable end of the roller while the other end of the roller continues to be supported in cantilever fashion.

Double-sleeved electrostatographic roller

A noise reduction sleeve that fits over a printing sleeve while the printing sleeve is being slid onto or off of a respective cylindrical with the aid of compressed air exiting from holes in the outer surface of the cylinder. The noise reduction sleeve is an open-ended cylinder of felted fibrous material of a length equal to or slightly longer than the printing sleeve, with an axial wall. The noise reduction cylinder has a long section, slightly shorter than the printing sleeve, with an inside diameter slightly larger than the outside diameter of the printing sleeve. The remaining length of the noise reduction sleeve is crimped down to an inside diameter slightly less than the outside diameter of the printing sleeve.
