Abstract:
A printhead chip for an inkjet printhead, the printhead chip comprisinga substrate; and a plurality of nozzle arrangements that is positioned on the substrate, each nozzle arrangement comprising nozzle chamber walls and a roof that define a nozzle chamber with the roof defining an ink ejection port that is in fluid communication with the nozzle chamber; an actuator that is displaceable, in a substantially rectilinear manner, with respect to the substrate; an ink-ejecting mechanism that is angularly displaceable with respect to the substrate to eject ink from the ink ejection port; and a translation to rotation conversion mechanism interposed between the actuator and the ink-ejecting mechanism to convert rectilinear movement of the actuator into angular displacement of the ink-ejecting mechanism.
