Method of driving inkjet printhead

摘要

Provided is a method of driving an inkjet printhead in which a driving pulse is applied to a piezoelectric actuator to change volume of a pressure chamber filled with ink so that an ink droplet is ejected through a nozzle (110) connected to the pressure chamber by a change in pressure according to a change in the pressure of the pressure chamber, in which the volume of the droplet ejected through the nozzle is changed by constantly maintaining a rising time (T R ) of the driving pulse and adjusting a duration time (T D ) of a maximum voltage (V P ) of the driving pulse.
