ABSTRACT:
A pressure wave pulse having a maximum pressure P1 and a width T generated from a piezoelectric element moves in a longitudinal direction. A pressure wave pulse having a maximum pressure Q and a width T generated from another piezoelectric element moves in any opposite direction. When the two pressure wave pulses overlap each other, a synthetic wave having a magnitude P and a width T is generated to thereby jet ink from a nozzle. At this time, a pressure having a magnitude greater than the magnitude P is temporarily applied several times to nozzles adjacent to the nozzle. However, a duration of the pressure applied is not enough to jet the ink from the adjacent nozzles.
