Abstract: A recording device includes a facing portion disposed facing a liquid discharge head and a wiper configured to wipe the head surface of the liquid discharge head by moving in the medium conveying direction with respect to the liquid discharge head. The facing portion is movable, to a recording position at which the facing portion faces the liquid discharge head and a retreat position to which the facing portion retreats from the recording position. The wiper is provided at the facing portion switchably between a first posture in which the wiper is configured to wipe the head surface and a second posture in which the wiper is farther from the head surface than in the first posture. The wiper wipes the head surface when the facing portion moves along the medium conveying direction with the wiper being in the first posture.
