Abstract

A means is disclosed for use in aerodynamically cleaning a photoreceptor. The means comprises a cleaning nozzle assembly and pneumatic positioning linkage as shown in the Figure. In the configuration shown, the nozzle assembly will be drawn toward the photoreceptor by gravity while being controlled for elevation by the pneumatic control circuit. A counter spring may be used to negate the gravity force on the nozzle assembly and also to provide other compensation. Force generated by the air pressure differential across the sensing nozzle will tend to retract the nozzle from the photoreceptor, however, with incorporation of the counter spring, should the po-sitioning control become inoperative due to air supply malfunction, the sensing nozzle would stay retracted and thereby prevent any damage to the photoreceptor. Positioning of each nozzle end is accomplished through two sets of two biasing bellows Al and A2.
