ABSTRACT:
A dual polarity commutated roll attracts toner and debris particles loosened into a particle cloud from the photoreceptor surface by an acoustical horn. The particles are attracted to and adhere to the commutated roll, whether right or wrong sign (i.e. positive or negative), and are removed from the roll, as the roll rotates, by a scraper blade. The particles are collected in a waste container as the particles are removed from the roll surface by the scraper blade. Residual particles that are not attracted to the commutated roll, are removed from the photoreceptor surface by a spots blade. The cleaning system does not contact the photoreceptor, thus, increasing cleaner and photoreceptor life.
