Abstract
There is provided a drive method of a liquid discharge apparatus including a first liquid discharge section having a first piezoelectric element applying a pressure to a liquid in a first pressure chamber be communicated with a first nozzle, a first drive line 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, a second liquid discharge section having a second piezoelectric element applying a pressure to a liquid in a second pressure chamber be communicated with a second nozzle. The method includes: detecting a potential of 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.
