Abstract:
An ink jet print head having a plurality of plates bonded together, the plurality of plates including a first plate and a second plate spaced from the first plate, the print head comprising:a nozzle in the first plate for ejecting ink onto a receiving surface;a manifold between the first plate and the second plate, the manifold being fluidically coupled to the nozzle;a vibration disruption chamber vertically spaced from the manifold for reducing mechanical vibrations within the printhead, wherein the vibration disruption chamber includes a first vibration disruption chamber and a second vibration disruption chamber horizontally spaced from the first vibration disruption chamber, wherein at least one of the plurality of plates is between the first vibration disruption chamber and the second vibration disruption chamber;an ink flow path from the manifold to the nozzle;a pressure chamber located along the ink flow path between the manifold and the nozzle; anda transducer coupled to the pressure chamber, the transducer being driven to eject ink through the nozzle.
