1. A liquid discharge apparatus comprising:
a liquid discharge head in which a nozzle is opened;
a carriage mounting the liquid discharge head;
a carriage moving mechanism configured to move the carriage;
a carriage motor configured to drive the carriage moving mechanism;
an output unit configured to output a discharge determination signal according to whether or not a liquid is discharged normally from the nozzle by an inspection for discharging the liquid from the nozzle in a case that the inspection is performed with the carriage in a predetermined position; and
a controller configured to carry out a determination of whether or not the liquid is discharged normally from the nozzle based on the discharge determination signal output from the output unit in a case that the inspection is performed, wherein
in response that a first condition is satisfied, as a first discharge determination process, the controller causes the liquid discharge head to perform the inspection after causing the carriage moving mechanism to move the carriage to the predetermined position, and
in response that a second condition which is different from the first condition is satisfied, as a second determination process, the controller causes the liquid discharge head to perform the inspection, without causing the carriage moving mechanism to move the carriage to the predetermined position.
