Original Abstract Submitted
An inspection signal output circuit including an electrode. The inspection signal output circuit outputs an inspection signal indicating an electrical change in the electrode when a head is driven to eject liquid from a nozzle toward the electrode. A controller performs an inspection operation sequentially for a plurality of nozzles. The inspection operation includes driving the head to eject liquid from the nozzle toward the electrode, acquiring the inspection signal output from the inspection signal output circuit, and determining whether there is an abnormality in ejection of liquid in the nozzle based on the acquired inspection signal. The controller performs, as the inspection operation, a first-type inspection of acquiring the inspection signal in a first order for the plurality of nozzles, and a second-type inspection of acquiring the inspection signal in a second order for the plurality of nozzles. The second order is different from the first order.
