Abstract
A liquid injection device includes a driving signal generation circuit generating a driving signal, and a driving signal supply circuit supplying a portion of, or an entirety of, the driving signal to the actuator. The driving signal generation circuit generates at least one driving pulse included in a dedicated large dot driving signal before a small dot driving signal and a medium dot driving signal. The driving signal supply circuit includes a small dot supplier supplying the small dot driving signal to the actuator; a medium dot supplier supplying the medium dot driving signal, and not supplying the small dot driving signal, to the actuator; and a large dot supplier supplying the small dot driving signal, the medium dot driving signal and the dedicated large dot driving signal to the actuator.
