Abstract:
A printhead chip for an inkjet printhead, the printhead chip comprisinga substrate; and a plurality of nozzle arrangements positioned on the substrate, each nozzle arrangement comprising a nozzle chamber structure that defines a nozzle chamber in which ink is received; an ink-ejecting member that is operatively positioned with respect to the nozzle chamber so that displacement of the ink ejecting member results in ejection of ink from the nozzle chamber; at least one actuator that is positioned on the substrate, the, or each, actuator being displaceable with respect to the substrate on receipt of a driving signal; and a motion transmitting structure interposed between the actuator and the ink-ejecting member so that displacement of the actuator relative to the substrate is transmitted to the ink-ejecting member so that ink is ejected from the nozzle chamber.
