1. A liquid ejection apparatus comprising:
a liquid ejection head having a nozzle configured to eject liquid;
a signal output circuit configured to, when inspection driving is performed by the liquid ejection head, output a determination signal indicating whether the nozzle is an abnormal nozzle, the inspection driving being driving the liquid ejection head to eject liquid from the nozzle for checking whether the nozzle is the abnormal nozzle;
a recovery device configured to perform a recovery operation of discharging liquid from the nozzle;
a memory; and
a controller configured to:
receive a first signal, the first signal being a power-on signal indicating that power of the liquid ejection apparatus is turned on;
in response to receiving the first signal, perform the inspection driving and, in response to determining that the determination signal transmitted from the signal output circuit indicates that the abnormal nozzle exists, store flag information in the memory, the flag information indicating that the recovery operation needs to be performed;
after storing the flag information in the memory, receive a second signal different from the first signal; and
in response to receiving the second signal and determining that the memory stores the flag information, control the recovery device to perform the recovery operation.
