Abstract: An electrophotographic reproduction device includes a pressure roll fuser whereat toner carried by a sheet of paper is fused onto the paper's surface by the application of both heat and pressure as the sheet passes through a pressure fusing nip. The pressure nip is formed by pressure engagement of a heated fusing roll to an unheated backup roll. A multilayer cloth wick (35) rubs against a portion of the hot roll's toner engaging surface, and thereby supplies release oil to this surface. When the wick's outer cloth layer (81) becomes contaminated with toner and the like, the operator activates a manually releasable stitch means which is associated with the wick's multiple layers. This action allows manual removal of the wick's top contaminated layer (81), thereby exposing a clean cloth surface (82) for subsequent engagement to the hot roll's toner engaging surface.

Abstract: An electrophotographic hot roll fuser is manually movable from an operative position within an electrophotographic reproduction device, to an inoperative position where the fuser is available for cleaning, inspection or sheet jam clearance. When the fuser is in its inoperative position, a manually operable handle is accessible for operation. Operation of this handle moves various operating components, such as sheet guides, apart, thereby facilitating manual sheet jam clearance. Subsequently, when the handle is manually returned to its original position, all sheet guides and like components are accurately relocated to their original operative positions.
