Drive method of liquid discharge apparatus

A drive method of a liquid discharge apparatus including a liquid discharge head that includes a nozzle, a pressure chamber communicating with the nozzle, a piezoelectric element that is configured to apply a pressure to a liquid in the pressure chamber, a drive line coupled to the piezoelectric element, and a resistor for measuring a temperature of the liquid in the pressure chamber, in which the piezoelectric element has a first electrode, a second electrode, a piezoelectric body disposed between the first electrode and the second electrode, and the resistor is made of the same material as any of the first electrode, the second electrode, and the drive line, the method comprising:

• executing a non-printing process of preventing a liquid from being discharged toward a recording medium after executing a first printing process of printing a first image on the recording medium by a liquid discharged from the nozzle and before executing a second printing process of printing a second image on the recording medium by a liquid discharged from the nozzle;
• and
• detecting a potential of the resistor when a state of a potential applied to the drive line is in a state of causing no liquid to be discharged from the nozzle during an execution period of the non-printing process,
• wherein a support section that supports the recording medium facing the nozzle is heated to a set temperature by a heater, and
• the set temperature in the second printing process is corrected based on a result of detecting the potential of the resistor in the non-printing process.
