Patent number: 4942433Abstract: A release liquid applying device of the known rotating wick type engages and is rolled by a fusing roller as it applies liquid to the roller. When resin based stock is used, a brake prevents rotation of the wick by the roller. This reduces the oil applied and reduces a tendency the rolling wick has to leave a pattern of locally excessive liquid in the oil on the roller.Type: GrantFiled: May 15, 1989Date of Patent: July 17, 1990Assignee: Eastman Kodak CompanyInventor: Paul O.

Patent number: 4766456Abstract: A RAM system suitable for use in copier and printing machines having a relatively slow (i.e. 2 inches per second) process speed while avoiding the prior art problem of excess oil application, particularly outside the copy area. The RAM system contains a supply of release agent material which permits operation without frequent addition of oil to the supply yet without fear of oil spillage.The RAM system comprises a very thin (i.e. 0.006 inches thick) wick one end of which contacts a supply of release agent material such as low viscosity silicone oil while an intermediate portion thereof is held in contact with a fuser roll member.An oil reservoir containing a pad is provided. The pad serves as the supply of oil for the one end of the wick. The majority of the oil is contained in the pad, therefore, the problem of spillage found in prior art devices is obviated.Type: GrantFiled: March 31, 1986Date of Patent: August 23, 1988Assignee: Xerox CorporationInventor: Robert G. Pirwitz

Patent number: 4751548Abstract: A heat and pressure fuser for fixing a toner image to a copy sheet in a xerographic copier has a heated fuser roll cooperating with a backup roll to form a nip through which the copy sheets are passed for fusing. In order to prevent toner offset the fuser roll is provided with a coating of silicone rubber or Viton (trademark) and the outer surface is supplied with a film of liquid release agent. The release agent is contained in a sump and fed to an applicator having a wick bearing against the fuser roll. Static buildup on the fuser roll is avoided because the wick is electrically conductive and is connected to earth potential via the copier frame providing a charge leakage path for the fuser roll. In a preferred form, the wick comprises a woven fabric in which the weft threads are electrically conductive, each such conductive thread comprising one or more stainless steel fibers entwined with a plurality of heat-resistive nylon, e.g. Nomex (trademark), fibers.Type: GrantFiled: May 12, 1987Date of Patent: June 14, 1988Inventor: David J. Lawson

Patent number: 4743943Abstract: 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 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 becomes contaminated with toner and the like, the operator acitvates a manually releasable stitch which is associated with the wick's multiple layers. This action allows manual removal of the wick's top contaminated layer, thereby exposing a clean cloth surface for subsequent engagement to the hot roll's toner engaging surface.Type: GrantFiled: January 12, 1987Date of Patent: May 10, 1988Assignee: International Business Machines CorporationInventors: Lawrence Adams, Jr., Reid W. Gunnell
