Method of stirring liquid in droplet discharge head and droplet discharge apparatus

摘要

In a method of stirring liquid in a droplet discharge head in which droplets of the liquid are discharged from a plurality of nozzle openings by driving piezoelectric elements provided to each of the nozzle openings, drive conditions of the piezoelectric elements are varied and the liquid that corresponds to the piezoelectric elements is caused to flow at different pressures.
