<p>PROBLEM TO BE SOLVED: To provide a liquid jetting device capable of executing a predetermined flushing operation rationally without making standby time in the case where the flushing operation is performed by a plurality of kinds of driving signals for flushing having different waveforms.SOLUTION: A liquid jetting device includes: a liquid jetting head body including a nozzle opening for discharging ink in a pressure generating chamber; and control means for generating a driving signal S2 for flushing besides a driving signal S1 for usual discharge for performing normal discharge of ink, and for performing a flushing operation by driving pressure generating means by the driving signal S2 for flushing. The driving signal S2 for flushing generated by the control means includes a driving signal S21 for standard flushing having the waveforms common to a plurality of kinds of ink, and a driving signal S22 for individual flushing having the waveforms unique to the ink kind in one cycle in series, and it is controlled so that flushing is performed by repeating a cycle including the driving signal S21 for standard flushing and the driving signal S22 for individual flushing for a predetermined number of times.</p> |
