摘要： A liquid-jet head selectively forms a large dot or a small dot. The large dot is ejected when a plurality of pulse signals are selected, and the small dot upon selection of a smaller number of the pulse signals. There is a contraction of the pressure generating chamber to eject a droplet through the nozzle, and a vibration damping step. The drive waveforms are set to implement this approach, and have particular characteristics.
