ABSTRACT:
An ink jet print head chip that includes a substrate that defines a plurality of ink inlet channels. A plurality of nozzle chamber structures is on the substrate to define nozzle chambers in fluid communication with the ink inlet channels and an ink ejection nozzle in fluid communication with each nozzle chamber. Drive transistor circuitry is positioned on the substrate and is connectable to data and power supplies. A plurality of elongate actuators are each fast with the substrate at one end to receive actuating signals from the drive transistor circuitry to be displaceable towards and away from the substrate. A plurality of ink ejection members is fast with respective actuators at opposite ends. Each ink ejection member is positioned in a respective nozzle chamber such that displacement of the respective actuators results in the ejection of a drop of ink from the ink ejection nozzle. The transistor circuitry includes traces that are interposed between each actuator and the substrate and oriented substantially orthogonally to a longitudinal axis of each respective actuator.
