  • Patent number: 4093367
    Abstract: A non-impact printing apparatus which employs xerographic techniques to develop a latent image on a transparent photoreceptor and transfer it therefrom to a receiving medium.
    Type: Grant
    Filed: April 18, 1975
    Date of Patent: June 6, 1978
    Assignee: Xerox Corporation
    Inventors: Roger H. Eichorn, deceased, BY Lincoln First Bank of Rochester, executor, Morton Silverberg
  • Patent number: 4046472
    Abstract: An imaging apparatus in which an electrostatic latent image is developed on an insulating web at a development station after which the web is transported to a platen capable of supporting a receiving surface. The web is transported from the development location to the platen in a plane parallel to the axis of the platen. The image is then transferred to a receiving surface supported by the platen. The imaging, development and transfer are controlled by a control logic circuitry.
    Type: Grant

  • Patent number: 3946230
    Abstract: An original and a heat sensitive member are inserted as a sandwich into a copying machine and fed past a combined imaging and transfixing or fusing station where radiation is applied to the sandwich to thermally impart a latent image of the original to the heat sensitive member. Thereafter, the original is separated from the heat sensitive member and ejected from the machine. The heat sensitive member on the other hand, continues onwardly to a developing station where toner particles are applied to develop the latent image. Next, the heat sensitive member loops back towards the imaging and transfixing station, and a copy medium is brought into engagement with the developed image. The copy medium and the heat sensitive member are then passed into the imaging and transfixing or fusing station.
