There is provided a liquid ejection apparatus including: a liquid ejection head that includes nozzles; a signal output circuit that outputs a signal that varies depending on whether at least part of the nozzles includes a discharge-defective nozzle; and a controller. The controller is configured to discharge a liquid on a medium by using a partial discharge mode; perform determination, for at least one nozzle included in the nozzles based on the signal from the signal output circuit, about whether the discharge-defective nozzle is included therein; and set, based on the signal from the signal output circuit, the part of the nozzles not to include the discharge-defective nozzle when the liquid is discharged from the liquid ejection head on the medium by using the partial discharge mode and when the controller has determined that the discharge-defective nozzle is included in the nozzles.
