ABSTRACT:
An ink jet printhead chip includes a substrate that defines a plurality of ink inlet channels. A plurality of nozzles is positioned on the substrate and is in fluid communication with the ink inlet channels. A plurality of elongate micro-electromechanical actuators is fast with the substrate at one end, an opposed end being displaceable relative to the substrate on receipt of an electrical drive signal. Each opposed end is operative on a respective nozzle to eject ink from the nozzle. Control circuitry and drive circuitry for each actuator is positioned on the substrate and interposed between the actuator and the substrate.
