Abstract:
A liquid ejecting device includes: an ejector including: a piezoelectric element displacing corresponding to a drive signal potential; a pressure chamber changing volume corresponding to the piezoelectric element displacement; and a nozzle communicating with the pressure chamber, and ejecting liquid from the pressure chamber; and a detector detecting residual vibrations produced by the ejector after piezoelectric element displacement. The detector detects the residual vibrations in a third period when the drive signal having a drive waveform is supplied to the piezoelectric element. The drive waveform being set to a first potential in a first period, a second potential in a second period, and a third potential in the third period. The volume of the pressure chamber in the second period is smaller than the volume in the first period. The volume of the pressure chamber in the third period is larger than in the second period.

Claim (Index 11):
The liquid ejecting device as defined in  claim 10 ,\n the drive waveform being designed so that a difference between the third potential and the first potential is larger than a difference between the second potential and the third potential.
