Liquid ejecting apparatus and print head

A liquid ejecting apparatus comprising:

• an ejection section including
• a piezoelectric element that is driven by a drive signal in a unit period defined by a timing signal,
• a pressure chamber filled with a liquid and having a volume changed according to driving of the piezoelectric element, and
• a nozzle ejecting the liquid in the pressure chamber according to the change in volume of the pressure chamber;
• a detection section detecting a potential of the piezoelectric element;
• and
• a determination section determining an ejection state of the ejection section according to a detection result of the detection section using a determination mode selected from among a plurality of determination modes including a first determination mode and a second determination mode, wherein
• when the piezoelectric element is driven by the drive signal in another unit period preceding one unit period,
• the determination section determines the ejection state of the ejection section using the first determination mode according to a detection result of the detection section in the one unit period, and
• when the piezoelectric element is not driven by the drive signal in the other unit period,
• the determination section determines the ejection state of the ejection section using the second determination mode according to the detection result of the detection section in the one unit period.
