  • Patent number: 12043752
    Abstract: The present teachings include a flow coating solution, a fuser member and an image forming apparatus. The fuser member includes a substrate and flow coating solution applied onto the substrate. The outer layer includes a flow coating solution including a fluoroelastomer, a nucleophilic crosslinking agent and a non-functional polydimethylsiloxane having the formula: wherein n is from 100 to 20,000. The flow coating solution includes an effective solvent selected from the group consisting of N-methyl 2-pyrrolidone, dimethyl formamide, and dimethyl sulfoxide.
    Type: Grant
    Filed: June 29, 2022
    Date of Patent: July 23, 2024
    Assignee: XEROX CORPORATION

  • Patent number: 8066366
    Abstract: A release agent applicator applies release agent to an imaging drum and absorbs release agent metered from the drum to extend the operational life of an image drum maintenance unit. The applicator includes a reservoir for storing release agent, the reservoir having a plurality of perforations for enabling release agent to seep from the reservoir, a containment membrane for wicking release agent from the perforations of the reservoir, and a delivery layer for delivering release agent from the containment membrane to an imaging drum, the delivery layer having pores in a range of about 50 ?m to about 200 ?m.

  • Patent number: 7764914
    Abstract: A fuser belt assembly of a xerographic marking device is provided with an endless fuser belt having an inner side and an outer side, a pressure pad movable between a cammed-in position in which the pressure pad contacts an inner side of the fuser belt to press an outer side of the fuser belt against a fuser roll to form a fusing nip, and a cammed-out position in which the pressure pad does not press the fuser belt against the fuser roll. The pressure pad includes two or more embedded pressure sensors for sensing a load of the pressure pad in the cammed-in position, and one or more preload adjustment screws for adjusting the load on the pressure pad based on the sensed pressure pad loads.

  • Patent number: 7540600
    Abstract: A release agent applicator applies release agent to an imaging drum and absorbs release agent metered from the drum to extend the operational life of a image drum maintenance unit. The applicator includes a reservoir for storing release agent, the reservoir having a plurality of perforations for enabling release agent to seep from the reservoir, a containment membrane mounted to the reservoir for wicking release agent from the perforations of the reservoir, and a delivery layer mounted to the containment membrane for delivering release agent from the containment membrane to an imaging drum that is in contact with the delivery layer. The delivery layer is matched to the containment membrane to maintain a saturation rate for the delivery layer in a predetermined range and the delivery layer has an uptake rate for release agent contacting an external boundary of the delivery layer that is greater than a release agent supply rate from the containment membrane to the delivery layer.
