Abstract
A liquid discharging apparatus includes: a liquid discharging head having nozzles; a purge mechanism which performs purge of discharging liquid from the nozzles; a signal outputting circuit which outputs signals depending on whether each of the nozzles is a failure nozzle which does not satisfy a predetermined discharging performance; a memory which stores, with respect to each of the nozzles, a value of an failure parameter regarding a number of times each of the nozzles is continuously determined to be the failure nozzle; and a controller. The controller performs failure nozzle determination with respect to at least a part of the nozzles as to whether each of at least the part of the nozzles is the failure nozzle, based on a signal from the signal outputting circuit, and updates the value of the failure parameter in the memory, based on a result of the failure nozzle determination.
