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.
