Abstract:
A method of controlling a liquid ejection head controls a liquid ejection head including a liquid pressurizing chamber, nozzles communicating with the liquid pressurizing chamber, and a pressure generating device that generates pressure in the liquid pressurizing chamber based on a drive waveform. The method includes generating a preliminary ejection drive waveform with a predetermined number of successive drive pulses aligned in descending order of length of drive pulse intervals of the drive pulses, with each of the drive pulse intervals set to an integral multiple of a natural vibration period of the liquid pressurizing chamber, and applying the generated preliminary ejection drive waveform to the pressure generating device to cause the liquid ejection head to perform a preliminary ejecting operation.
