Patent ID: 8567888

Claim:
A liquid ejecting apparatus comprising: nozzles which eject liquid; a pressure chamber which communicates with the nozzles; a pressure generating element which changes the pressure of liquid in the pressure chamber and ejects the liquid from the nozzles; a driving signal generating unit that generates a driving signal including a first ejection wave form and a second ejection wave form which causes the liquid to be ejected to the pressure generating element, and a first transition element between the first ejection wave form and the second ejection wave form; and a driving unit which controls the supplying of the driving signal to the pressure generating element, wherein each of the first ejection wave form and the second ejection wave form includes a decompression element that causes the liquid to be decompressed in the pressure chamber, a compression element that causes the liquid to be compressed in the pressure chamber after the decompression by the decompression element, and a decompression element that causes the liquid to be decompressed in the pressure chamber after the compression by the compression element, the first ejection wave form is set to a first reference electric potential at a starting end and a terminal end, the second ejection wave form is set to a second reference electric potential at the starting end and the terminal end, an electric potential difference between the first reference electric potential and a lowest electric potential of the first ejection wave form is smaller than an electric potential difference between the second reference electric potential and a lowest electric potential of the second ejection wave form, the first reference electric potential is lower than the second reference electric potential, and an electric potential of the first transition element is changed from one of the first reference electric potential and the second reference electric potential to the other thereof.
