Abstract
A printhead chip for an inkjet printhead includes a substrate. A plurality of nozzle arrangements is positioned on the substrate. Each nozzle arrangement includes a nozzle chamber structure that defines a nozzle chamber in which ink is received. An ink-ejecting member 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 is positioned on the substrate. The, or each, actuator is displaceable with respect to the substrate on receipt of a driving signal. A motion transmitting structure is 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.
