Abstract
A liquid discharge apparatus is provided including a liquid discharge head, a cap, and a wiper. The liquid discharge head includes a nozzle plate having thereon a nozzle for discharging a liquid. The cap caps a surface of the nozzle plate. The wiper moves relative to the nozzle plate to wipe the surface of the nozzle plate. The surface of the nozzle plate has a cap contact region that is contactable with the cap. The wiper starts wiping from a wiping start position that is disposed between both end parts of the cap contact region in a direction of wiping. The wiper comes into contact with the surface of the nozzle plate at the wiping start position and moves in a first direction to wipe the surface of the nozzle plate, and thereafter moves in a second direction opposite the first direction to wipe the surface of the nozzle plate.
