摘要： A cleaning bath is provided on a base of a liquid ejection apparatus. A cleaning liquid supply section and a cleaning liquid discharge section are connected to the cleaning bath. The cleaning liquid supply section supplies cleaning liquid to the cleaning bath. The cleaning liquid discharge section drains the cleaning liquid from the cleaning bath. After having formed dots, a head unit is moved to the position immediately above the cleaning bath. Reflective mirrors are then immersed in the cleaning bath in the vicinity of an inlet pipe through which the cleaning liquid is introduced into the cleaning bath. An ejection head is also immersed in the cleaning bath in the vicinity of an outlet pipe through which the cleaning liquid is drained from the cleaning bath.
