Patent ID: 8425023

Claim:
A liquid ejecting apparatus comprising: a liquid ejecting head including a continuous liquid path and a pressure generating section, the liquid path containing a pressure space and a nozzle opening, the pressure generating section causing pressure fluctuations to occur in liquid within the pressure space, the liquid ejecting head ejecting droplets through the nozzle opening by driving the pressure generating section; a driving signal generating section capable of generating a driving signal containing a driving pulse that drives the pressure generating section; a drive control section that supplies the driving pulse contained in the driving signal generated by the driving signal generating section to the pressure generating section; and a sealing section that seals a nozzle-formed surface of the liquid ejecting head, wherein the driving pulse includes a first pulse for causing discharge of droplets and a second pulse, the second pulse being generated to the pressure generating section at a generation interval T set in a range represented by the following expression: ( n− 1/4) Tc<T <( n+ 1/4) Tc where Tc is a natural oscillation period for the liquid within the pressure space and where n=1, 2, 3 . . . (a natural number), and the sealing section seals the nozzle opening of the liquid ejecting head when the pressure generating section is driven by the second pulse.
