ABSTRACT:
A wiper device of a liquid ejection apparatus includes a first wiper that wipes a nozzle surface defined in a liquid ejection head, a second wiper that wipes a side surface of the liquid ejection head extending in a direction intersecting the nozzle surface, and a drive mechanism that drives the first and second wipers to move between respective standby positions and wiping positions. The second wiper is formed separately from a cap that seals the nozzle surface of the liquid ejection head. The drive mechanism operates to move the second wiper to the corresponding wiping position independently from the first wiper. In this manner, independent wiping of the side surface of the liquid ejection head is performed when desired.
