摘要： An inkjet printhead having a bezel structure to remove ink bubbles. The inkjet printhead includes a channel plate having an ink channel, actuators formed on the channel plate to provide driving forces to eject the ink, and an ink-supply bezel coupled to the channel plate. The ink-supply bezel includes an ink reservoir that is connected to an ink inlet and stores ink that is to be supplied to the ink channel, an ink supply port through which ink is supplied to the ink reservoir, and an air discharge port through which bubbles that are removed from the ink of the ink reservoir are discharged. The ink supply port and the air discharge port can be formed closed to both ends of the top surface of the ink reservoir, respectively. The ink supply port can have a bottom end lower than that of the air discharge port. The ink reservoir can include a sloped ceiling surface. Therefore, ink bubbles can be effectively removed from the ink before the ink is supplied to the ink channel.

摘要： An inkjet printing apparatus according to example embodiments may include a flow channel plate including an ink inlet for introducing ink, a pressure chamber containing the introduced ink, and a nozzle connected to the pressure chamber and configured to eject ink. A piezoelectric voltage applier may apply a piezoelectric driving voltage to the piezoelectric actuator in such a way that the volume of the pressure chamber is reduced so as to eject an ink droplet. An electrohydrodynamic voltage applier may apply a first electrohydrodynamic driving voltage and a second electrohydrodynamic driving voltage to the electrohydrodynamic actuator. The first electrohydrodynamic driving voltage may generate a jet from the ink droplet such that the jet is ejected towards a printing medium, and the second electrohydrodynamic driving voltage (which has an opposite polarity to that of the first electrohydrodynamic driving voltage) may restore the ink droplet to the nozzle.
