US Classification:

4273722, 427374, 427379, 427384, 428 368, 428 369, 4283139, 428327, 428421, 428447

Abstract:

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.

US Classification:

399334, 399329, 399330

Abstract:

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.

Abstract:

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.

Abstract:

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.

International Classification:

US Classification:

156 94, 15624413

Abstract:

There is described a method for producing a fuser member. A substrate is obtained and a fluoropolymer sleeve is positioned around an outer surface of the substrate. An elastomer is injected between the outer surface of the substrate and an inner surface of the sleeve to form a fuser member and demolded. The fuser member is conditioned at a first temperature of between about 30 C. below the melting point of the fluoropolymer and about 50 C. above the melting point of said fluoropolymer for about 1 to about 20 minutes. The fuser member is then optionally held at a second temperature of about 220 C. to about 260 C. for a period of about 4 hours to about 20 hours.

US Classification:

399333

Abstract:

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 10Ω/cm.
