Abstract:
A printhead includes a substrate defining a plurality of ink inlet channels; a drive circuitry layer; and a plurality of nozzle arrangements. Each nozzle arrangement comprises a wall portion bounding a respective ink inlet channel, a crown portion defining an ink outlet, and a skirt portion depending from the crown portion. The crown, skirt and wall portions define a nozzle chamber. The printhead further includes an elongate actuator provided within the nozzle chamber and connected to the crown portion at one end and anchored to the substrate at an opposite end; and conductive pads provided at the anchor point of the elongate actuator, the conductive pads being provided between the elongate actuator and the substrate. The elongate actuator receives electrical signals from the drive circuitry via the conductive pads, and upon receipt of electrical signals from the drive circuitry, displaces towards and away from the substrate.
