Abstract
A wiper cleaner unit moves a wiper-off part to a capping position orthogonally relative to a direction in which inkjet heads are disposed in synchronization with movement of a cap holder, thereby wiping off wiper blades in a standby position orthogonally relative to the direction in which the inkjet heads are disposed. This allows the wiper-off part to clean the wiper blades off ink droplets. Consequently, cleaning unevenness of a print unit due to the wiper blades is avoidable.
