ABSTRACT:
An apparatus for enhancing transfer of a developed toner image from an image bearing member to a support substrate in an electrostatographic printing machine including a resonator suitable for generating vibratory energy arranged in line contact with the back side of the image bearing member for uniformly applying vibratory energy to the image bearing member. The toner release enhancing system includes a vacuum source, including a vacuum plenum substantially enclosing the resonator and defining an opening adjacent the image bearing member, wherein the vacuum source provides sufficient force at the vacuum plenum opening to draw the image bearing member toward the resonator, and an integral air regulator system for providing substantially constant air pressure at the interface between the resonator and the image bearing member.
