  • Electrode type print head for printing apparatus and method of manufacturing the same
    Patent number: 6302526
    Abstract: This specification discloses an electrode type print head for the printing apparatus and the method for manufacturing the same. The print head is placed in the inkjet cartridge of an inkjet-printing device. The print head comprises a substrate and a flexible nozzle plate with an ink reservoir formed in between. The flexible nozzle plate is attached onto the substrate, and the electrode set of the flexible nozzle plate corresponds to that of the substrate. When currents of different polarities are provided thereon, an absorptive force is generated to pull the flexible nozzle plate closer to the substrate. A pushing force jets the ink out of the print head and onto a printing media to achieve the goal of inkjet printing.
