  • Patent number: 8469685
    Abstract: The present invention provides an apparatus for allowing the resurfacing of a cylindrical member in a printer having a fuser member that is externally heated by a heater roller. The apparatus includes providing a cylindrical member having an outer surface of a high temperature fluorothermoplastic. When it is determined that the outer surface is in need of resurfacing, the fuser member is removed from the printer, and the cylindrical member is mounted in the place of the fuser member. The cylindrical member is rotated at a speed of at least 1 rpm while engaging the outer surface of the fuser member with the heater roller normally used to heat the fuser member at a pressure of at least 5 psi at a temperature of at least 10° C. below the fluorothermoplastic melting temperature for a time sufficient to resurface the outer surface of the cylindrical member.

  • Patent number: 8304016
    Abstract: A method of making a fuser member having an annealed outer surface comprising: providing an outer layer comprising compatible first and second fluorothermoplastics over an outer substrate surface, wherein the first fluorothermoplastic is a crosslinkable polymer and the second fluorothermoplastic is a linear polymer; curing the outer layer to crosslink the first fluorothermoplastic whereby the resulting crosslinked first fluorothermoplastic and the linear polymer second fluorothermoplastic form a semi-interpenetrating polymer network (SIPN); and annealing an outer surface of the outer layer by contacting the fuser member with applied pressure against a heated surface, without first sintering the second fluorothermoplastic linear polymer through application of heat alone.

  • Publication number: 20110159276
    Abstract: A fuser member comprising: a substrate comprising an outer substrate surface; and an outer layer comprising compatible first and second fluorothermoplastics disposed over the outer substrate surface, wherein the first fluorothermoplastic is a crosslinked polymer and the second fluorothermoplastic is a linear polymer and wherein the compatible first and second fluorothermoplastics form a semi-interpenetrating polymer network (SIPN). The SIPN provides a relatively compliant layer in comparison to use of the crosslinked polymer alone, and avoids the need for sintering of a layer formed from the linear polymer alone. The SIPN may be formed from an aqueous coated composition of polyperfluoroalkoxy-tetrafluoroethylene (PFA) and THV Fluoroplastics (FLC) polymers along with a soluble organic primary amine for crosslinking the THV Fluoroplastics (FLC).

  • Patent number: 7560140
    Abstract: An apparatus for enabling the uniform application of a layer of a coating composition to a tubular substrate includes a shaft, and upper and lower circular rim members of equal diameter that are concentrically attached to the shaft. A pneumatically inflatable tube disposed on each circular rim member has an outer diameter that is variable with changes in its internal pressure. A first flexible cylindrical sheet in contact with the inflatable tubes has parallel edges that form a first slit sufficiently wide to permit movement of the first sheet in response to pressure variation in the tubes. A second flexible cylindrical sheet surrounding the first cylindrical sheet has parallel edges that form a second slit sufficiently wide to permit movement of the second sheet also in response to pressure variation. The second slit is laterally displaced from the first slit, and the second cylindrical sheet has a diameter nearly equal to the specified diameter of the substrate.
