ABSTRACT:
An ultrasonic transducer located under the photoreceptor belt provides vibrational energy to the surface to separate toner particles from the surface. The transducer is positioned such that it is located directly opposite the cleaning nip of the brush cleaner. The transducer reduces the adhesion of the toner to the photoreceptor surface, thereby allowing the brush to operate at reduced interference and voltage. The reduced interference and voltage results in toner being collected only at the very tips of the brush fibers thus, allowing more effective detoning of the brush.
