ABSTRACT:
A liquid ejecting apparatus includes two liquid discharge heads, a wiper unit, and an actuating mechanism. Each of the two liquid discharge heads has a nozzle face on which at least one nozzle opening for discharging liquid is formed. The two liquid discharge heads are located so that the nozzle faces of the two liquid discharge heads face each other. The wiper unit is pressed against each of the nozzle faces of the two liquid discharge heads at a position at which the wiper unit is placed between the nozzle faces of the two liquid discharge heads. The actuating mechanism reciprocally moves the wiper unit relatively along the nozzle faces of the two liquid discharge heads.
