Abstract
A liquid ejection apparatus includes a liquid ejection head having a plurality of nozzles, a determination circuit, a clock, and a controller. The controller is configured to determine whether the clock is in an on or off state. In response to determining that the clock is in an on state, the controller is configured to perform an inspection process at a first time. In the inspection process, the controller drives the liquid ejection head to eject liquid from a nozzle of the plurality nozzles and receive a determination signal that is output from the determination circuit in response to ejection of liquid from the nozzle of the plurality of nozzles. In response to determining that the clock is in an off state, the controller is configured to perform the inspection process at a predetermined time that is a time after the clock is returned to an on state.
