Abstract
A liquid discharge apparatus which causes a liquid to be discharged through a first nozzle by applying a driving signal to a first driving element, and causes a liquid to be discharged through a second nozzle by applying the driving signal to a second driving element, and which, with respect to the first nozzle, determines on the basis of an image formed by causing the liquid to be discharged through the first nozzle whether or not the first nozzle causes a liquid discharge failure, and, with respect to the second nozzle, determines on the basis of a detection signal which is obtained by applying the driving signal to the second driving element whether or not the second nozzle corresponding to the second driving element causes a liquid discharge failure.
