Abstract
A printhead module assembly includes a printhead integrated circuit (IC) assembly. The printhead IC assembly includes a plurality of ink ejection nozzles arranged to form staggered rows. The printhead IC assembly defines a plurality of ink channels for supplying ink to the ink ejection nozzles. A flexible printed circuit board (PCB) is electrically connected to supply both power and data to the IC assembly. A support sheet defines a plurality of ink holes. The IC assembly is bonded to the support sheet so that the ink channels are aligned with the ink holes.
