Drive method of liquid discharge apparatus

A drive method of a liquid discharge apparatus including a first liquid discharge section having a first nozzle, a first pressure chamber that is configured to communicate with the first nozzle, a first piezoelectric element that is configured to apply a pressure to a liquid in the first pressure chamber, a first drive line that is configured to be coupled to the first piezoelectric element, and a first resistor that is configured to measure a temperature of the liquid in the first pressure chamber, and a second liquid discharge section having a second nozzle, a second pressure chamber that is configured to communicate with the second nozzle, and a second piezoelectric element that is configured to apply a pressure to a liquid in the second pressure chamber, in which each of the first piezoelectric element and the second piezoelectric element has a first electrode, a second electrode, and a piezoelectric body disposed between the first electrode and the second electrode, and the first resistor is made of the same material as any of the first electrode, the second electrode, and the first drive line, the method comprising:

• detecting a potential of the first resistor when a state of a potential applied to the first drive line is in a state of causing no liquid to be discharged from the first nozzle, during an execution period of a first printing process of printing a first image on a recording medium by a liquid discharged from the second nozzle without discharging a liquid from the first nozzle,
• wherein a drive signal to be supplied to the second piezoelectric element is corrected based on the potential of the first resistor.
