Abstract
There is provided a drive method of a liquid discharge apparatus including a liquid discharge head that includes a nozzle, a pressure chamber, a piezoelectric element, a drive line, and a resistor that is made of the same material as any of the first electrode, the second electrode, and the drive line. The method includes: 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 and before executing a second printing process of printing a second image on the recording medium; 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.
