Abstract: When inspection driving is performed by a liquid ejection head, a signal output circuit outputs a determination signal indicating whether a nozzle is an abnormal nozzle. A controller receives a first signal different from a signal responsive to a user operation of the liquid ejection apparatus; in response to receiving the first signal, performs the inspection driving and, in response to determining that the determination signal transmitted from the signal output circuit indicates that the abnormal nozzle exists, stores flag information in a memory. The flag information indicates that a recovery operation needs to be performed. After storing the flag information, the controller receives a second signal that is the signal responsive to the user operation of the liquid ejection apparatus; and in response to receiving the second signal and determining that the memory stores the flag information, controls a recovery device to perform the recovery operation.

Abstract: A liquid ejection apparatus includes a first circuit to output a determination signal indicating that ejecting ink is in failure, a second circuit to output a temperature signal indicating a temperature, a recovery device to perform a recovery operation, and a controller. The controller causes a recovery device to perform a first recovery operation based on a first failure-nozzle data in response to determining that a first temperature and a second temperature satisfy a predetermined condition.
