Abstract
A method for recovery of a recording head includes cleaning liquid supplying operation, wiping operation, and backflow operation. The recording head is connected to a cleaning liquid tank for storing cleaning liquid via a cleaning liquid supplying path. In the backflow operation, a liquid supply mechanism makes the cleaning liquid in the cleaning liquid supplying path to flow backward in a direction pointing from the cleaning liquid supplying openings to the cleaning liquid tank. The recording head includes an ink ejection region in which ink ejection openings are open, and a cleaning liquid supplying region which is arranged upstream of the ink ejection region in a wiping direction and in which cleaning liquid supplying openings are open. The backflow operation is performed after a wiper passes the cleaning liquid supplying region and before the wiper reaches the ink ejection region.
