  • Ink jet print head with damping feature
    Patent number: 6260963
    Abstract: An ink jet print head includes one or more vibration disruption chambers for reducing mechanical vibrations within the print head. The chambers are vertically spaced from ink manifolds to dissipate energy within the print head and alter the bending modes of the print head jet stack. The chambers may contain a discontinuous material that enhances their damping effects.
