  • Roller fuser system with fusing member temperature control for printing
    Patent number: 7680424
    Abstract: Internally-heated external rollers transfer heat rapidly to a fuser roller in an electrostatographic printer. Stored media process set points, input image content and input media type data are used to regulate the heat transfer rate by varying the nip width between the heated external rollers and the fuser roller. The rate of heat transfer and the rate of heat transfer adjustment are sufficiently rapid that many different media weights and types may be mixed in a print run without restrictions on media run lengths, without collation requirements per run, and without productivity losses due to slowing of feed rate for heavier receivers.
    Type: Grant
    Filed: September 28, 2007
    Date of Patent: March 16, 2010
    Assignee: Eastman Kodak Company
    Inventors: James H. Hurst, John L. Hryhorenko, Muhammed Aslam, Douglas J. Kostyk
  • System for control of fusing member temperature
    Patent number: 7570894
    Abstract: A fuser control system and method are provided for improving the image control of printing systems, including digital front-end processors, color printers and post-finishing system. This automatic image control system, including measurement and calibration, by registering the thermal load measurements.
