Abstract: A grounding method and apparatus for robustly grounding a photoreceptor assembly, including a conductive photoreceptor drum, in a xerographic image producing machine. The grounding apparatus includes (a) a flange including a first portion having a first diameter and a second portion having a second and smaller diameter; (b) a conductive plating formed on said flange presenting a relatively large conductive surface area for contactably assembling against walls of the conductive photoreceptor drum; and (c) an electrical connector for electrically connecting the large conductive surface area of the conductive plating to an electrically conductive drive shaft of the xerographic image producing machine.

Abstract: A container is provided for delivering a supply of particles for use in a developer unit of an electrophotographic apparatus. A resistor member, is permanently associated with the container. When the container is associated with the electrophotographic apparatus, the resistance of the resistor member is identified and a fault signal is communicated to a display when the incorrect configuration of the container is identified as being used in the electrophotographic apparatus. Also provided is a method of determining the configuration of a container in a printing or copying apparatus.

Abstract: A system for identifying a supply accessory in a device. The system includes a device identifier in the supply accessory and a controller adapted to measure a value of the device identifier, compare the measured value with a predetermined value and determine if the supply accessory corresponds to the device.
