Liquid ejecting apparatus and print head

A liquid ejecting apparatus comprising:

• a plurality of ejection sections including
• a first ejection section including a first piezoelectric element that is driven by a drive signal, a first pressure chamber filled with a liquid and having a volume changed according to driving of the first piezoelectric element, and a first nozzle ejecting the liquid into the first pressure chamber according to the change in volume of the first pressure chamber, and
• a second ejection section including a second piezoelectric element that is driven by the drive signal, a second pressure chamber filled with the liquid and having a volume changed according to driving of the second piezoelectric element, and a second nozzle ejecting the liquid into the second pressure chamber according to the change in volume of the second pressure chamber;
• a common liquid chamber supplying the liquid to the plurality of ejection sections;
• a detection section detecting a potential of the first piezoelectric element;
• and
• a determination section determining an ejection state of the first 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
• the determination section
• determines the ejection state of the first ejection section using the first determination mode according to the detection result of the detection section when the second piezoelectric element is driven by the drive signal, and
• determines the ejection state of the first ejection section using the second determination mode according to the detection result of the detection section when the second piezoelectric element is not driven by the drive signal.
