  • Publication number: 20080013991
    Abstract: A fuser assembly comprises a fusing member and a pressure member, where the fusing member and the pressure member cooperatively rotate to form a fuser nip. The fuser is arranged so that the pressure member speed is reduced with respect to the fusing member speed, thus forming a reduced pressure member speed. The reduced pressure member speed stretches or retards the surface of the fusing member elastomer enough to assist in stripping or peeling the media sheet lead edge from the fusing member. As a result of initially stripping or peeling the media sheet lead edge, the remaining media body likewise is assisted to be stripped or peeled from the fusing member. In various embodiments the media stripping or peeling process is assisted by means of one or more air knives, one or more stripping fingers, or any combination of these items.

  • Publication number: 20070206981
    Abstract: A sheet centering stripping assembly is provided for stripping a fused sheet exiting a fusing nip having a still malleable toner image thereon. The sheet centering stripping assembly includes (a) a first air knife device for directing a first flat stream of pressurized air at a first force to contact a first side of the fused sheet exiting the fusing nip; and (b) a second air knife device for directing a second flat stream of pressurized ionized air at a second force to contact a second and opposite side of the fused sheet exiting the fusing nip, thereby equalizing air flow above and below the fused sheet to prevent smudging of the malleable toner image and minimize curling of such fused sheet.

  • Publication number: 20070134033
    Abstract: A fuser assembly includes a pressure member motion speed reduction device which slows the pressure member speed when the printed paper lead edge exits the nip. The temporarily slower pressure member speed stretches or retards the surface of the fusing member elastomer enough to assist in peeling the lead edge from the fusing member thereby allowing the rest of the paper to peel off. In one embodiment, the paper stripping or peeling process is assisted by means of one or more air knives, one or more stripping fingers, or any combination of these items.

  • Publication number: 20070104521
    Abstract: A pressure roll used in a fusing step of an electrophotographic system is provided with a higher abrasion material at the ends of the roll. This higher abrasion material extends the useful life of the roll and reduces debris caused by deterioration of the pressure roll.

  • Publication number: 20070020002
    Abstract: A release agent application apparatus includes a liquid-permeable member, a first release agent metering member abutting the liquid-permeable member, and a pump operatively connected to the liquid-permeable member to pump the release agent therethrough.

  • Publication number: 20060193661
    Abstract: An improvement in a Release Agent Management system that alleviates the buildup of dirt, toner and paper debris on a wick in the system includes a metering roll, a supply of release agent material into which the wick is positioned and a pair of metering blades positioned on opposite sides of the metering roll before and after a nip formed between the metering roll and a donor roll. A first metering blade meters release agent material onto the metering roll and a second blade scrapes the surface of the metering roll to remove contaminants before the surface of the metering roll reaches the supply of release agent material in order to prevent contaminants from plugging the wick and thereby reduce the effectiveness of the wick.
