Abstract:
A hierarchically aligned inkjet printhead includes a plurality of printhead units and a base holding the printhead units. Each printhead unit includes a plurality of drop ejector array devices, each of which includes at least one drop ejector array; a first butting edge having a first mechanical alignment feature; and a second butting edge having a second mechanical alignment feature. Each printhead unit includes an ink manifold that is fluidically connected to each of the plurality of drop ejector array devices in the printhead unit; and a mounting member to which the drop ejector array devices are affixed. A pair of opposing alignment edges of each printhead unit are substantially parallel to the butting edges of the drop ejector array devices. A first of the opposing alignment edges includes an outwardly-extending projection, and a second of the opposing alignment edges includes a niche that is substantially complementary to the projection.

Claim (Index 17):
A method of assembling a hierarchically aligned inkjet printhead, the method comprising:\n assembling a plurality of printhead units, each printhead unit being assembled by:\n affixing a plurality of drop ejector array devices to a mounting member, wherein adjacent drop ejector array devices in the printhead unit are butted end to end at adjacent butting edges, and are mechanically aligned using mechanical alignment features on the butting edges of the drop ejector array devices; and \n affixing the mounting member to an ink manifold such that the ink manifold is fluidically connected to each of the drop ejector array devices in the printhead unit; \n positioning a first printhead unit on a base by loosely engaging a plurality of first locating features on the first printhead unit with a corresponding first plurality of second locating features on the base; positioning a second printhead unit on the base by loosely engaging a plurality of first locating features on the second printhead unit with a corresponding second plurality of second locating features on the base; pushing the second printhead unit to produce a relative motion toward the first printhead unit, wherein the relative motion is guided during a first time interval by inserting an outwardly extending projection of a first alignment edge of the first printhead unit into a substantially complementary niche in an adjacent second alignment edge of the second printhead unit; continuing to push the second printhead unit toward the first printhead unit until a mechanical alignment feature on an endmost first butting edge of the first printhead unit interlocks with an adjacent substantially complementary mechanical alignment feature on an endmost second butting edge of the second printhead unit; and securing the first printhead unit and the second printhead unit to the base.
