20090022897 | High temperature silicone processing of fuser structure - This is a process to restore compression set properties of a silicone rubber fuser structure that has been damaged during the coating of the silicone with Teflon; Teflon is a registered trademark of DuPont. This restoration is achieved by re-baking the coated fuser roll at temperatures of 175° C. to 275° C. This will improve the compression set and will give the fuser structure improved life and provide better image quality. | 01-22-2009 |
20100189943 | INTERMEDIATE LAYER COMPRISING CNT POLYMER NANOCOMPOSITE MATERIALS IN FUSERS - Exemplary embodiments provide a fuser member containing an intermediate layer and methods for forming the intermediate layer and the fuser member. In one embodiment, the fuser member can include a substrate, a resilient layer, a surface layer and an intermediate layer disposed between the resilient layer (e.g., a silicone rubber layer) and the surface layer (e.g., a fluoroplastic of PFA or PTEE). The intermediate layer can include a CNT/polymer composite containing a plurality of carbon nanotubes in a polymer matrix. The surface layer and the fuser member can thus be treated at a temperature of about 250° C. or higher. | 07-29-2010 |
20100278569 | APPARATUSES USEFUL FOR PRINTING AND METHODS OF TREATING MARKING MATERIAL ON MEDIA - Apparatuses useful for printing and methods of treating marking material on media are provided. An exemplary embodiment of the apparatuses includes a first member including a first outer surface; and a roll including a second outer surface forming a nip with the first outer surface. The second outer surface includes an inner portion having first and second axially-spaced edges, a roughened first high-friction surface axially outward from the first edge and a roughened second high-friction surface axially outward from the second edge. The first and second high-friction surfaces extend circumferentially around the roll and have a higher roughness than the inner portion. The inner portion and the first and second high-friction surfaces contact the first outer surface at the nip, and the first and second high-friction surfaces lie outside of a media path through the nip. | 11-04-2010 |
20110143143 | FUSER COATING COMPOSITION AND METHOD OF MANUFACTURE - The present teachings include a coating composition which includes a liquid, fluoropolymer particles, carbon nanotubes, and a dispersant. The dispersant has a thermal degradation temperature below the melting temperature of the fluoropolymer particles. | 06-16-2011 |
20110217529 | FUSER MANUFACTURE AND ARTICLE - According to an embodiment a method of making a fuser member is described. The method includes, obtaining a silicone layer disposed on a substrate and coating a primer composition including an aqueous dispersion of a fluorelastomer and a curing agent on the silicone layer. A topcoat composition is coated on the primer composition which includes a fluoroplastic dispersion. The primer composition and the topcoat composition are heated to form the fuser member. | 09-08-2011 |
20130059085 | FUSER COATING COMPOSITION AND METHOD OF MANUFACTURE - The present teachings include a coating composition which includes a liquid, fluoropolymer particles, carbon nanotubes, and a dispersant. The dispersant has a thermal degradation temperature below the melting temperature of the fluoropolymer particles. | 03-07-2013 |
20130116369 | FUSER COATING COMPOSITION AND METHOD OF MANUFACTURE - The present teachings include a coating composition of a powder of fluorine containing particles, aerogel particles and poly(alkylene carbonate). A method of making a fuser member and the fuser member resulting therefrom is also provided. | 05-09-2013 |
20140016974 | FUSER SYSTEM - The present teachings provide a fuser system for use in a xerographic apparatus. The fuser system includes a fuser roller and a pressure roller. The fuser roller and the pressure roller create a nip. The fuser roller has an outer layer of carbon nanotubes dispersed in a fluoropolymer wherein the carbon nanotubes comprise from about 0.1 weight percent to about 10 weight percent of the outer layer. The pressure roller comprises a static dissipative outer surface having a surface resistivity of less than about 10 | 01-16-2014 |
