Patent ID: 7673953

Claim:
A liquid ejecting apparatus, comprising: a liquid ejecting head including, a pressure chamber provided in communicating with a nozzle opening, and a pressure generating unit capable of changing a pressure of liquid contained in the pressure chamber; and a driving signal generating unit capable of generating a first driving signal and a second driving signal, the first driving signal and second driving signal including a plurality of discharge pulses having a expansion component expanding the pressure chamber and a contracting component contracting the pressure chamber, wherein the first driving signal including a first discharge pulse and a second discharge pulse generating after the first discharge pulse; the second driving signal including a third discharge pulse and a fourth discharge pulse generating after the third discharge pulse; the beginning of the fourth discharge pulse is generated after the beginning of the second discharge pulse; and a period of time between the beginning of the contracting component of the second discharge pulse and the end of the contracting component of the fourth discharge pulse is corresponded to a characteristic vibration period of a liquid contained in the pressure chamber.
