Abstract

Special features have been developed to improve scorotron efficiency, manufacturability, reliability, and serviceability for the office copier environment. Unidirectional rotation of the photoreceptor allows the higher efficiency of a combination corotron/ scorotron to be used. A simplified screen configuration, an extruded shield, and high quality molded plastic end blocks simplify manufacture. A wraparound shield, a manual cleaner for corona and screen wires, and a foolproof slide mount, improve reliability and serviceability. Thus a scorotron is able to provide the improved consistency of photoreceptor sensitization necessary for high quality solid area reproduction copies. Charging nonuniformities caused by photoreceptor fatigue, thickness variation, temperature sensitivity, and miscellaneous charge acceptance variables, are significantly reduced.
