Abstract
A xerographic printer includes a cleaning system having an electrically biased brush and a spots blade downstream of the brush. At various times a “lubrication stripe” dense toner is placed on a photoreceptor to lubricate the spots blade. In order for the lubrication stripe to reach the spots blade, the bias on the brush is momentarily decreased while the lubrication stripe moves past the brush. Also, the specific color of the lubrication stripe can be selected for various situations.
