FUSER FOR ELECTROPHOTOGRAPHIC MACHINE

摘要

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.
