ABSTRACT:
An ink jet printhead includes a substrate that defines a plurality of ink inlets. A drive circuitry layer is positioned on the substrate. A plurality of nozzle arrangements is arranged on the substrate. Each nozzle arrangement includes a nozzle chamber structure positioned on the substrate and defining a nozzle chamber in fluid communication with a respective ink inlet, and an ink ejection port in fluid communication with the nozzle chamber. An actuator is connected to the drive circuitry layer and is displaceable with respect to the substrate on receipt of an electrical signal from the drive circuitry layer. An ink ejection member is operatively positioned with respect to the nozzle chamber and is displaceable when the actuator is displaced such that ink is ejected from the ink ejection port. The ink ejection member is configured so that the ink ejection member obstructs a flow of ink from the nozzle chamber into the inlet at a certain position in a displacement path of the ink ejection member.
