Abstract:
1. A printing mechanism that comprises an elongate support structure; a pair of busbars that are mounted on the support structure; a plurality of printed circuit boards that are mounted on the support structure to be electrically connected to the busbars, each printed circuit board including print engine control circuitry that is configured to control operation of a number of printhead chips; a plurality of ink distribution structures that are mounted on the support structure and connectable to a supply of ink; and a plurality of printhead modules that are mounted on respective ink distribution structures, each printhead module having a carrier and a printhead chip positioned on the carrier, each printhead chip having a plurality of nozzle arrangements that are positioned on a wafer substrate, each nozzle arrangement incorporating a micro-electromechanical actuator for ejecting ink from a nozzle chamber, and being mounted on a respective ink distribution assembly, a number of the printhead chips being connected to the print engine control circuitry such that each nozzle arrangement can receive data signals from the print engine control circuitry.
