  • Inline purge capability (purge while run) to improve system productivity during low area coverage runs
    Patent number: 7493057
    Abstract: An electrostatic printing machine having a plurality of color stations having a system for maintaining a preset toner age in each of the plurality of color stations, including: determining a toner age for each of the plurality of color stations; determining if purge while run is required based on the toner age for each of the plurality of color stations; defining an area on a unused portion of an imaging frame for a purge patch, the defining includes sizing a plurality of purge patch regions wherein each of the purge patch regions may have a different size; allocating each of the plurality of purge patch regions to at least one color plane from a group of color separations.
    Type: Grant
    Filed: September 29, 2006
    Date of Patent: February 17, 2009
    Assignee: Xerox Corporation

  • Xerographic setup and operating system for electrostatographic reproduction machines
    Patent number: 5051781
    Abstract: An automatic xerographic set up and monitoring process for a multi-mode electrostatographic machine in which a corona charge intercept value is obtained and used to optimally set corona charging levels for different modes, optimum flash exposure levels obtained, ID lamp intensity correlated with flash exposure levels, and xerographic process parameters set for each different mode.
