Title: Pagewidth inkjet printhead assembly with data and power supply mounted on ink distribution assembly

Abstract: A pagewidth printhead assembly includes an elongate ink distribution manifold that defines a longitudinally and centrally oriented printhead integrated circuit recess and longitudinal rows of transverse slots that converge towards and open into, the recess. An elongate printhead integrated circuit incorporating a plurality of micro-electromechanical ink ejecting mechanisms is positioned in the recess to receive ink from the slots. An ink storage assembly is mounted on the manifold and defines ink storage chambers in fluid communication with respective rows of slots. Busbars are mounted on the ink storage assembly opposite the printhead integrated circuit. Flexible TAB films interconnect the busbars with the printhead integrated circuit. The TAB films extend around sides of the ink storage assembly. A cover is mounted on the ink storage assembly. A securing mechanism secures the busbars and TAB films in position.
