Abstract:
A method of driving a liquid ejection head includes preparing a liquid ejection head including first and second flow paths, and a piezoelectric element, a first step of applying a first voltage, which expands the second flow path, to the piezoelectric element while a meniscus of a liquid recessed from an orifice toward the second flow path is formed in a first flow path to move the meniscus to the second flow path, a second step of applying a second voltage, which contracts the second flow path, to the piezoelectric element while the meniscus that moves toward the first flow path is positioned in the second flow path to move the liquid to the first flow path, and a third step of applying a third voltage, which expands the second flow path, to the piezoelectric element to eject the liquid from the orifice after the liquid projects from the orifice.
