ABSTRACT:
A liquid electrophotography fluid containment and belt tracking device has a rubber or other elastomeric profile fixed to both edges of a photoconducting belt to provide both belt tracking control and fluid edge effects control. The part of the profile that extends from the inside surface of the belt is used as a tracking rail. A mating profile is machined into the belt rollers to provide tracking control. The part of the profile that extends from the outside surface of the belt is used to seal the edge to the squeegee roller to prevent fluid from moving around the end of the squeegee roller.
