Abstract
The seal member can be held in close contact with the head unit by being elastically deformed according to the shape of the head unit including the head (seal close contact operation). Accordingly, the drying of the nozzles can be prevented by isolating the nozzles inside the seal members from the atmosphere outside the seal members. Further, the cap can be brought into contact with the head unit while the seal member is separated from the head unit (cap contact operation). In this cap contact operation, the cap in contact with the head unit allow air flows between the outside and inside of the cap. At the time of purging, the cap contact operation is performed, whereby the cap is caused to face the nozzles and the ink flowing out from the nozzles is received by the cap.
