Abstract

A magnetic brush cleaning station is disclosed for use in cleaning residual toner from the photoconductor of a xerographic reproduction device. The figure is a side view of the cleaning station. Photoconductor drum 10 is about eighteen inches long. Drum 10 rotates counterclockwise (CCW) about axis 11 at a constant speed. In an exemplary reproduction device, the photoconductor is first charged to a negative 800 volts. The photoconductor is then selectively discharged at an imaging station (not shown), to leave a latent electrostatic image thereon. Thereafter, the latent image is toned with positively charged toner. The toner is then transferred to a sheet of paper, whereupon residual toner which is left on the photoconductor after transfer is cleaned from the photoconductor by operation of the cleaning station.
