  • Patent number: 5313256
    Abstract: A device for embossing electrophotographically printed sheets is operatively disposed downstream of a fusing station. The device includes a rotatable member having a relief defined on an edge thereof for pressing into the sheet. The rotatable member is rotated by the same mechanism that drives the fusing station.
    Type: Grant

    Date of Patent: May 17, 1994
    Assignee: Xerox Corporation
    Inventors: Raphael F. Bov, Jr., William C. Howe
  • Patent number: 4766462
    Abstract: A reproducing machine in which an electrostatic latent image recorded on a photoconductive member is developed with a liquid developer material comprising at least a liquid carrier having pigmented particles dispersed therein. The developed image is transferred from the photoconductive member to a sheet of support material. The sheet of support material, with the developed image thereon, passes through a housing. In the housing, heat and pressure are applied to the sheet of support material to vaporize the liquid carrier and to fuse the pigmented particles to the sheet of support material in image configuration. An interior surface of the housing is cooled to liquefy the vaporized liquid carrier thereon.

  • Patent number: 4733272
    Abstract: A reproducing machine in which a liquid image including a liquid carrier having pigmented particles dispersed therein is transferred to a sheet of support material. In the operative mode, when the sheet of support material having the liquid image thereon is present, a fuser applies heat thereto to remove liquid carrier therefrom so as to dry the sheet of support material, and fuse the pigmented particles thereto in image configuration. In the standby mode, when the sheet of support material is not present, the fuser still generates heat. The liquid carrier removed from the sheet of support material by the fuser is collected in a condenser. Air flowing from the condenser passes through a filter to remove residual liquid carrier therefrom, in the standby mode, heated air from the fuser is directed to the filter to regenerate the filter.

  • Patent number: 4731636
    Abstract: An apparatus in which a developing liquid used in an electrophotographic printing machine to develop an electrostatic latent image on a photoconductive surface is reclaimed. The developing liquid is vaporized to dry the wet copy sheet. The developing liquid vapor enters the chamber of a housing and condenses on the surface of a cooling fluid as it passes therethrough. The developer liquid is immiscible in the cooling fluid and floats on the surface thereof so as to exit from the outlet port of the chamber of the housing for recirculation to the development system.
