Pagewidth inkjet printhead incorporating power and data transmission circuitry

摘要

A pagewidth inkjet printhead includes an elongate ink distribution assembly connectable to an ink supply. A printhead chip is mounted on the ink distribution assembly to receive ink from the ink distribution assembly. A cover is fast with the ink distribution assembly. Power and data transmission circuitry is interposed between the cover and the ink distribution assembly and connected to the printhead chip to provide the printhead chip with power and data signals.
