Abstract

At a dot cycle (T3), a dummy burst signal as well as a jet burst signal are supplied for a vibration exciter to drive it so that the vibration exciter can provide liquid with a periodic radiation pressure. The dummy burst signal is so determined as to jet no droplet, with a smaller number of pulses and so on. That allows a stable motion of meniscus of ink and it is thereby possible to stably jet the droplets. With this control provided is a technique to improve a shape of an ink surface from which the droplets are created and stably jet the droplets when a liquid jet unit for jetting the droplets from a liquid surface is driven.
