    Abstract: An inkjet printhead having a cantilever actuator, the inkjet printhead including a plurality of ink chambers containing ink to be ejected; a manifold containing ink to be supplied to the plurality of ink chambers; a plurality of restrictors supplying ink to the plurality of ink chambers from the manifold; a plurality of nozzles ejecting ink from the plurality of ink chambers; and a plurality of cantilever actuators each installed in each of the plurality of ink chambers and having one fixed end and the other deflectable end, such that pressure for ejection of ink is applied due to the deflection of the other end of the cantilever actuator to the ink inside the ink chamber. The cantilever actuator may be made of a bimorph element, eject ink through the nozzle from the ink chamber, and also prevent backflow of ink from the ink chamber to the restrictor by virtue of the deflection of the other end thereof. Since the cantilever actuator can have a greater displacement and can prevent backflow of ink, the size of the ink chamber needed to eject ink droplets of uniform volume can be reduced, and thus the number of channels per inch (CPI) of the inkjet printhead can be increased.
