ABSTRACT:
A cleaning station for removing residual toner from a moving toner transfer surface includes a rotating brush and a scraper blade that is held away from the toner transfer surface when toner images are being transferred to recording media, such as sheets of paper. On a periodic basis, when toner images are not being transferred to the recording media, the scraper blade is moved into contact with the toner transfer surface to remove agglomerated toner therefrom, with continued operation of the rotating brush.
