Abstract
When a liquid ejection head and a first wiping unit are moved relatively to clean a surface, the first wiping unit making a first wiping member travel in a first direction, a direction opposite to the first direction is used as a moving direction of the head with reference to the first wiping member in relative moving therebetween. When the head and a second wiping unit are moved relatively to each other to clean the surface, the second wiping unit making a second wiping member travel in a second direction having a component of a direction opposite to the first direction, a direction opposite to the second direction is used as a moving direction of the head with reference to the second wiping member in relative moving therebetween to move the second wiping unit and the head relatively to clean the same area on the surface.
