Abstract: A tensioning system that precisely sets and monitors tension in a photoreceptor belt and includes a stepper motor that is actuated by a controller to apply pressure to the photoreceptor belt through a roll over which the belt is mounted. A load cell is positioned with respect to a piston actuator to sense the pressure applied by the piston actuator against the photoreceptor belt and signals the controller which in turn actuates the stepper motor to bring the tension on the belt to a predetermined set amount.

Abstract: A high slope charging device including a DC portion followed by an AC portion. The high slope device includes an insulative shell housing, an electrode and a corona wire. The electrode is coupled to direct current power source which supplies a constant potential to the electrode thereby generating a corona at the electrode. An alternating current power source supplies an alternating voltage to the corona wire. The high slope device beneficially is designed such that both the electrode and the corona wire charge a charge retentive surface to the same potential.
