Abstract
A printer includes an inkjet head that includes a plurality of individual flow passages each including a nozzle and a manifold commonly communicating with the plurality of individual flow passages, a heater that heats ink in the manifold, and a temperature sensor that detects a temperature of ink in the manifold. After the heater heats ink in the manifold, liquid droplets are ejected from the nozzles of the inkjet head. Abnormal ejection of the nozzle is detected based on a detected change in a temperature of the ink in the manifold.
