Resonator coupling cover for use in electrostatographic applications

A system for enhancing transfer of toner from an image bearing member, comprising:

• means for applying vibratory energy to the image bearing member;
• a cover member interposed between said vibratory energy applying means and the image bearing member;
• vacuum means for drawing the image bearing member toward said cover member;
• and
• an adhesive layer situated between said vibratory energy applying means and said cover member for providing an adhesive bond therebetween.

An electrostatographic printing apparatus including a system for enhancing transfer of toner particles from an image bearing member, including a resonator assembly for applying uniform vibratory energy to the image bearing member, comprising:

• a vibratory energy producing element for generating the vibratory energy;
• a waveguide member coupled to said vibratory energy producing element for directing the vibratory energy to the image bearing member;
• a coupling cover interposed between said vibratory energy producing element and the image bearing member;
• and
• an adhesive layer situated between said vibratory energy producing element and the image bearing member for providing an adhesive bond therebetween.

A resonator assembly for applying uniform vibratory energy to an image bearing member, comprising:

• a vibratory energy producing element for generating the vibratory energy;
• a waveguide member coupled to said vibratory energy producing element for directing the vibratory energy to the image bearing member;
• a vacuum apparatus including a vacuum plenum defining an opening adjacent the image bearing member, wherein said vacuum apparatus provides sufficient force at said vacuum plenum opening to draw the image bearing member toward said waveguide member;
• and
• a coupling cover including a pair of resilient cap members, wherein each cap member is mounted on said vacuum plenum along the opening thereof so as to be interposed between the vacuum plenum and the image bearing member.

A system for enhancing transfer of toner from an image bearing member, comprising:

• means for applying vibratory energy to the image bearing member;
• vacuum means including a vacuum plenum including a pair of wall members having said vibratory energy applying means interposed therebetween, the wall members extending to a substantially common plane to define an opening adjacent the image bearing member, wherein said vacuum means provides sufficient force at said vacuum plenum opening to draw the image bearing member toward said vibratory energy applying means;
• and
• a cover member including a pair of resilient cap members, wherein each cap member is mounted on said vacuum plenum along the opening thereof so as to interposed between the vacuum plenum and the image bearing member.
