ABSTRACT:
In a xerographic printing apparatus, a charge device is used to apply a charge to a photoreceptor. The shuttle includes a wiper that cleans a sidewall of the charge device. A tab is disposed adjacent the sidewall to retain toner or dirt accumulated by the scraper. The tab is electrically insulative, and effectively covers the accumulated toner or dirt, to lower the possibility of arcing within the charge device.
