Vibration suppression and electromechanical damping apparatus for electrophotographic printing structures

摘要

An apparatus for suppressing print quality degradation due to vibrations in a printing machine structure. The apparatus comprises a vibration member having a structural resonance, a transducer, and means for damping vibrations. The transducer is mounted to the vibration member and produces electrical signals corresponding to mechanical vibrations of the vibration member. The damping means is connected across the transducer and is responsive to the electrical signals.
