Title: Dennis J Justus: Innovator in Electrostatic Copier Technology
Introduction
Dennis J Justus is a notable inventor based in Boulder, CO (US). He has made significant contributions to the field of electrostatic copiers, particularly through his innovative patent that enhances maintenance processes.
Latest Patents
One of his key patents is titled "Method and apparatus for drum corona current measurement and alignment." This invention provides a method and apparatus for enabling measurement of corona drum current in an electrostatic copier as a maintenance aid. The design features a rotatable drum that supports a photoconductor with a conductive backing connected to a ground current return path, which includes a slip ring. In maintenance mode, the ground path is opened, allowing drum current to flow through a current measuring circuit. This circuit includes a pair of jacks to which a measurement device may be connected. The current measuring circuit also develops a potential that indicates whether the current return path is grounded. This potential is coupled to a monitoring device, which can drive a display. The alignment method involves energizing a selected corona generator, interrupting the normal ground return path, and providing a current path from the photoconductor to a measurement device. At least two measurements are made while different portions of the corona generator are masked, providing valuable data for alignment.
