Abstract
Electrostatographic printing apparatus comprising an endless imaging surface and a blade cleaning station for removing residual toner particles therefrom, the blade cleaning station being positioned on top of the imaging surface at about the twelve o'clock position and including a cleaner sump housing containing a cleaning blade mounted on said sump to provide front and rear sump portions and in interference with the imaging surface for removing residual toner therefrom, the cleaner sump housing has an active toner moving device such as a rotatable paddle wheel which moves agglomerated cleaned toner away from the top of the cleaning blade to reduce the head height of toner that is agglomerated at the cleaning blade/photoreceptor interface.
