ABSTRACT:
An apparatus for cleaning an imaging surface with a hybrid cleaner that includes the implementation of a contamination seal in the cleaner unit. The contamination seal captures falling accumulated toner from the blade edge and in the brush nip, due to gravitation, which contaminates the xerographic area when the cleaner blade and disturber brush are retracted from the imaging surface. The contamination seal rests along the length of the blade portion that extends from the blade holder. In this position, the contamination seal does not touch the imaging surface to cause scratches nor does it interfere with the blade's ability to clean the imaging surface. Implementation of the contamination seal contains toner emission within the cleaner from the blade edge and brush nip.
