摘要:
A printing apparatus includes a guide member for directing sheets toward a transfer zone. The guide member defines a set of ribs which hold the sheets above the main surface of the guide member. Thus, any stray marking material which lands on the guide member is relatively unlikely to contact a sheet moving over the guide member.
摘要:
Toner removal device for removing residual toner and debris from a charge retentive surface (10) after transfer of toner images from the surface. This device is characterized by the use of a pair of electrically biased detoning rolls (114, 120), one for removing toner from a biased cleaner brush (100) for recirculation and use and the other for removing debris such as paper fibers and Kaolin from the brush. Placement of the detoning rolls is selected so that the brushes are located adjacent natural oscillation nodes of the brush, and closely spaced to the position where the cleaning brush leaves contact with the charge retentive surface. Cleaning blades (150) for the detoning rolls are integrally provided with holders (152) for insertion into receiving slots (154, 156) in the cleaning housing (106). Extrusion sleeves are provided for insertion into toner transport devices for removal for cleaning.
