Two-input, two-output fuzzy logic print quality controller for an electrophotographic printer
(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 ...
Three-input, three-output fuzzy logic print quality controller for an electrophotographic printer
(United States patent office, 1995-02-14)
A control method for optimizing print quality in an electrophotographic printer uses a fuzzy-logic technique with solid-area, halftone, and light toner density as control inputs, and scorotron voltage, ROS laser power, and ...
Method and apparatus for predicting the cycle-down behavior of a photoreceptor
(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 ...
