摘要： A wiping device includes a wiping member including a web to wipe an object to be wiped, and circuitry to cause the wiping member to perform a wiping operation to wipe the object to be wiped. The circuitry causes the wiping member to perform a first wiping operation to move the wiping member relative to the object to be wiped in a first direction to wipe the object to be wiped from a wiping start side of the first wiping operation, and perform a second wiping operation to relatively move the wiping member relative to the object to be wiped in a second direction different from the first direction, to wipe the object to be wiped from a wiping finish side different from the wiping start side of the first wiping operation with the wiping member.

摘要： 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.
