ABSTRACT:
A printhead integrated circuit (IC) for an inkjet printer, with a plurality of nozzle chamber structures positioned on a wafer substrate to define nozzle chambers and an ink ejection nozzle in fluid communication with each nozzle chamber, has drive control and drive circuitry connectable to data and power supplies, and a plurality of elongate actuators attached to the substrate for displacement towards and away from the substrate in response to actuating signals from the drive control and drive circuitry. A plurality of ink ejection members are attached to respective actuators, each ejection member being positioned for acting on ink within respective nozzle chambers to eject a drop of ink from the ink ejection nozzle. The drive control and drive circuitry has traces between each actuator and the substrate and oriented transverse to a longitudinal axis of each respective actuator.
