ABSTRACT:
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 cleaning voltage as outputs. The fuzzy-logic program involves two two-input error subset matrices, one for simultaneous readings of solid-area and halftone densities, and one for successive light toner density readings.
