ABSTRACT:
A pagewidth inkjet printhead is provided which comprises an elongate ink distribution assembly connectable to an ink supply. A printhead chip is mounted to the ink distribution assembly to receive ink from the ink distribution assembly and a plurality of positioning protuberances protrude from the ink distribution assembly. A power and data transmission film is positioned about the ink distribution assembly using the plurality of positioning protuberances. At least one power busbar is positioned about the ink distribution assembly also using the plurality of positioning protuberances. The positioning protuberances may protrude from an outer surface of the ink distribution assembly and the power and data transmission film can be a tape automated bonding (TAB) strip interconnecting the at least one power busbar and the printhead chip.
