Abstract:
A method of manufacturing a liquid ejection head having a plurality of passage modules that have individual passages, actuator modules that include a plurality of actuators and a drive unit and the liquid ejection head produced by the method. The method comprising ranking the actuator modules according to a magnitude of a capacitance of the actuators, classifying the passage modules into a terminal region group and a central region group, fixing the actuator modules to the passage modules so that the actuator modules that having a capacitance not less than a predetermined capacitance correspond to the passage modules in the terminal group and so that the actuator modules having a capacitance less than the predetermined capacitance in the actuator module ranking correspond to the passage modules in the central region group.
