Abstract
An ink jet drop-on-demand print head comprises a plurality of electromechanical transducers, and ink from a manifold is conveyed to the transducers. The fluid path between the transducers and the corresponding nozzle in the nozzle array comprises a resilient dual function means. The dual function means not only provides the fan-in section but also seals the fluid path in fluid tight relation without the use of any adhesive or bonding material.
