  • Two-input, two-output fuzzy logic print quality controller for an electrophotographic printer 

    Hopkins, Mark (United States patent office, 1998-06-02)
    A control system for optimizing print quality in an electrophotographic printer uses a fuzzy-logic technique with only solid-area and half-tone density as control inputs, and only scorotron voltage and ROS laser power as ...

  • Method and apparatus for predicting the cycle-down behavior of a photoreceptor 

    Hopkins, Mark (United States Patent Office, 1994-10-11)
    Charges on a photoreceptor dissipate quickly before a latent image enters the development stage of the machine where the image is developed. The photoreceptor's charge potential before entering the developer is called the ...
