Liquid Ejection Apparatus

Abstract: a liquid ejection apparatus includes a first piezoelectric element, a first pressure chamber, a second piezoelectric element, a second pressure chamber, a nozzle flow path which communicates with the first pressure chamber and the second pressure chamber and which is provided with a nozzle, and a determination unit configured to determine a liquid state at the nozzle based on a first detection signal which represents a change in electromotive force of the first piezoelectric element after at least one of the first piezoelectric element and the second piezoelectric element is driven, and a second detection signal which represents a change in electromotive force of the second piezoelectric element after at least another of the first piezoelectric element and the second piezoelectric element is driven.
