Abstract
A liquid ejecting apparatus includes a liquid ejecting head, a driving signal generating section, a drive control section, and a sealing section. The liquid ejecting head includes a continuous liquid path and a pressure generating section. The liquid path contains a pressure space and a nozzle opening. The driving signal generating section generates a driving signal containing a driving pulse that drives the pressure generating section. The driving pulse includes a first pulse for causing discharge of droplets and a second pulse that is 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 of the liquid within the pressure space. The sealing section seals the nozzle opening of the liquid ejecting head when the pressure generating section is driven by the second pulse.
