Abstract:
A liquid jetting apparatus comprising:a head member having a nozzle, a pressure-changing unit that can cause pressure of liquid in the nozzle to change in such a manner that the liquid is jetted from the nozzle, a jetting-mode setting unit that can set a selected jetting mode from a plurality of jetting modes, a driving-signal generator that can generate a common jetting-driving signal, a driving-pulse generator that can generate a full-jetting driving pulse, based on the selected jetting mode and the common jetting-driving signal, and a full-jetting main controller that can cause the pressure-changing unit to operate, based on the full-jetting driving pulse, wherein the full-jetting driving pulse is used to fully cover an image unit of a recording medium with the liquid jetted from the nozzle, and wherein respective full-jetting drive pulses are different according to respective jetting modes.
