Abstract
There is provided a liquid ejection apparatus, including: a head; a signal output circuit; a discharge mechanism; a controller; and a memory in which association information is stored. The controller is configured to: diagnose a degree of defectiveness of the head based on a signal from the signal output circuit; and receive, from a user, an input of discharge amount information. In response to the input of the discharge amount information, the controller is configured to: control the discharge mechanism to discharge a liquid by a discharge amount corresponding to the discharge amount information; and change the association in the association information based on the discharge amount corresponding to the discharge amount information and a discharge amount that corresponds to the degree of the defectiveness of the head.
