Abstract
In a liquid droplet jetting mode of jetting liquid droplets, a controller controls a piezoelectric actuator to perform a liquid droplet jetting operation in which volume of a pressure chamber is decreased to a decreased volume smaller than a predetermined volume, and then the volume of the pressure chamber is increased to an increased volume greater than the predetermined volume, and the volume of the pressure chamber is again decreased to the decreased volume. On the other hand, in a warm-up mode of heating the liquid in the pressure chamber, the controller controls the piezoelectric actuator to perform at least one of a first warm-up operation in which the volume of the pressure chamber is changed repeatedly between the predetermined volume and the increased volume, and a second warm-up operation in which the volume of the pressure chamber is changed repeatedly between the predetermined volume and the decreased volume.
