ABSTRACT:
A printhead chip includes a substrate that incorporates drive circuitry and defines ink inlet channels. Nozzle chamber structures are positioned on the substrate. Each nozzle chamber structure defines a nozzle chamber in fluid communication with a respective ink inlet channel and an ink ejection port in fluid communication with the nozzle chamber. Ink ejecting mechanisms are pivotally displaceable with respect to the substrate to eject drops of ink from the ink ejection ports. Actuators are connected to the drive circuitry. Each actuator includes a force transmitting portion that is substantially linearly displaceable upon receipt of a signal from the drive circuitry and is connected to a respective ink ejecting mechanism to displace the ink ejecting mechanism pivotally with respect to the substrate.
