  • Single-pass, multi-color electrostatographic duplex printer
    Patent number: 6047156
    Abstract: A single-pass, multi-color electrostatographic duplex printer has a transfer member which is driven along a continuous path. Toner images of different colors are simultaneously electrostatically deposited in powder form in register with each other on the transfer member to form a multiple toner image. The substrate is fed into contact with the transfer member for transfer of the multiple toner image to at least one face of the substrate. The printer includes a heater for heating the multiple toner image on the transfer member in advance of the transfer of the image to the substrate.
    Type: Grant
    Filed: August 24, 1998
    Date of Patent: April 4, 2000
    Assignee: Xeikon N.V.
    Inventors: Jan Julien Irma De Bock, Etienne Marie De Cock, Daniel Frans Maria Van De Velde
  • Single-pass, multi-color electrostatographic printer with continuous path transfer member
    Patent number: 5893018
    Abstract: A single pass, multi-color electrostatographic printer includes a transfer member which is driven along a continuous path. Several toner images of different colors are electrostatically deposited in powder form in registration with each other on the transfer member to form a multiple toner image thereon. A substrate is fed into contact with the transfer member. The multiple toner image is thereby transferred to at least one face of the substrate. The printer includes heaters for heating the multiple toner image on the transfer member in advance of the transfer of the image to the substrate and cooling devices for cooling the transfer member following the transfer of the multiple toner image therefrom to the substrate to a temperature below the glass transition temperature T.sub.g of the toner, prior to the deposition of further toner images on the transfer member.

  • Single-pass, multi-color electrostatographic printer with intermediate transfer member
    Patent number: 5805967
    Abstract: A single-pass, multi-color electrostatographic printer has a transfer member which is driven along a continuous path. Toner images of different colors are simultaneously electrostatically deposited in powder form in register with each other on the transfer member to form a multiple toner image. The substrate is fed into contact with the transfer member for transfer of the multiple toner image to at least one face of the substrate. The printer includes a heater for the multiple toner image on the transfer member in advance of the transfer of the image to the substrate, and cooling capability for the transfer member following the transfer of the multiple toner image to the substrate, to a temperature below the glass transition temperature T.sub.g of the toner, prior to deposition of further toner images on the transfer member.
