INJECTION MOLDED INK JET MODULES

摘要

A print head includes an aperture plate and a plurality of duplicate, injection molded, jet modules that are coupled to the aperture plate. Each of the jet modules includes a plurality of jets and corresponding ink supply cavity that seals against the aperture plate and provides ink to the jets. Each jet module further includes a registration member and an edge alignment feature. The registration member holds the jet module in place relative to a corresponding registration member of the aperture plate. The edge alignment feature overlaps a corresponding alignment feature on a neighboring one of the jet modules in a z-direction and minimizes misalignment between the jet module and the neighboring jet module.

1. A print head comprising:
an aperture plate that defines a print-parallel surface and a z-direction normal thereto; and a plurality of duplicate, injection molded, jet modules coupled to the aperture plate, each of the jet modules comprising:
a plurality of j ets and corresponding ink supply cavity that seals against the aperture plate and provides ink to the jets;a registration member that holds the jet module in place relative to a corresponding registration member of the aperture plate; andan edge alignment feature that overlaps a corresponding alignment feature on a neighboring one of the jet modules in a z-direction, the edge alignment feature minimizing misalignment therebetween.
