Abstract

In the drawing, rotation of the photoreceptor 3 of a xerographic copying or printing machine generates air movement causing any loose toner particles to migrate throughout the surrounding area. Additional toner contamination is traceable to the developer brushes and doctor blade cleaners which engage the surface of the photoreceptor and strip air from the photoreceptor 3, and to the pressure drop caused by the rotating photoreceptor endbells 4 which draw high pressure air contaminated with toner out of the cleaner and developer.

In the drawing, rotation of the photoreceptor 3 of a xerographic copying or printing machine generates air movement causing any loose toner particles to migrate throughout the surrounding area. Additional toner contamination is traceable to the developer brushes and doctor blade cleaners which engage the surface of the photoreceptor and strip air from the photoreceptor 3, and to the pressure drop caused by the rotating photoreceptor endbells 4 which draw high pressure air contaminated with toner out of the cleaner and developer.

To eliminate or reduce such toner migration, it is proposed that the gap between the photoreceptor endbells 4 and the xerographic module side plates 6 be filled with a polyurethane foam seal 8 coated with Mylar. Seal 8 prevents the pressure drop due to air movement and reduces toner migration from the development or cleaning zone.

Mylar @ is a tradmark of E. I. DuPont.
