Abstract
A head-maintenance device includes a suction cap to cap a nozzle surface of a head to discharge liquid, a suction unit to suck the inside of the suction cap, an air-release channel communicating with the inside of the suction cap, a lid to close an opening of the suction cap, and processing circuitry. The processing circuitry performs an air-release channel suction operation to close the air-release channel and suck the inside of the suction cap by the suction unit, with the opening of the suction cap closed by the lid, and open the air-release channel with the inside of the suction cap in a negative pressure.
