Ink jet printhead chip with nozzle arrangements incorporating spaced actuating arms |
摘要 |
An ink jet printhead chip includes a substrate. A plurality of nozzle arrangements is positioned on the substrate. Each nozzle arrangement includes a nozzle chamber and an ink ejection port in fluid communication with the nozzle chamber. An actuator is connected to the substrate and is displaceable with respect to the substrate. An ink ejection mechanism is connected to the actuator and is operatively arranged with respect to the nozzle chamber to eject ink from the ink ejection port on displacement of the actuator. The actuator has an actuating arm that has active beams that are configured to be displaced upon receipt of the control signal. The active beams are spaced from corresponding passive beams in a plane that spans the substrate. The spacing is greater than one percent of a length of the actuating arm and less than twenty percent of the length of the actuating arm.
