Abstract

This disclosure relates to a cleaning system for various devices including photo-receptor cleaning, lithography, liquid developer doctoring and other surfaces which are cleaned or contacted by a blade member to clean the surface thereof. An interposition member is placed between the cleaning member, e.g., a cleaning blade, and the surface which the cleaning blade contacts. The interposition member extends between the cleaning member and the surface undergoing cleaning for improved removal of materials that collect at the nip formed between the cleaning member and the surface. For example, there is improved removal of dust, debris and the like from the area of the nip when the interposition member of the present disclosure is used. The interposition cleaning member preferably advances either continuously or intermittently in the nip area. This may be accomplished by using an interposition member, such as a web or film of material, wound upon a feed roller on one side of the nip area and collected by another roller on the other side of the nip area so that the interposition member passes beneath the cleaning member in the nip region where the cleaning member contacts the surface being cleaned. The interposition member may be any material which will remove the particles and other debris which collect at the area of the nip including plastic films, fiberglass or metal.
