Abstract
A liquid ejection apparatus includes a liquid ejection head having an array of nozzles each configured to eject liquid, a storage, and a controller. The storage stores first data including distribution patterns and causes of an ejection failure and second data including causes of an ejection failure and maintenance manners. In a case where the nozzles include a failure nozzle, the controller determines a cause of a currently-occurring ejection failure based on the first data, perform maintenance in a first maintenance manner associated with the cause based on the second data. In a case where the currently-occurring ejection failure due to the cause has been recovered a predetermined number of times by maintenance in the first maintenance manner, the controller is configured to change the first maintenance manner associated with the cause to a second maintenance manner in the second data.
