Abstract:
Provided is a recording head recovery system, which includes a recording head and a wiper. The recording head includes an ink ejection surface provided with an ink ejection region in which ink ejection ports are formed. The recording head is disposed on a wiping direction upstream side of the ink ejection region, and a cleaning liquid supply region in which cleaning liquid supply ports for supplying cleaning liquid are formed. A height position of a lower end part of the wiper when passing the cleaning liquid supply region is lower than a height position of the lower end part of the wiper when wiping the ink ejection region.

Claim (Index 8):
A recording head recovery system comprising:\n a recording head including an ink ejection surface provided with an ink ejection region in which a plurality of ink ejection ports are formed for ejecting ink onto a recording medium; a wiper configured to wipe the ink ejection surface in a predetermined direction; a wiper holding member for holding the wiper and moving the same along the ink ejection surface, the wiper holding member being capable of rotating about a rotation shaft extending in a head width direction perpendicular to a wiping direction in which the wiper wipes the ink ejection surface; a rotation mechanism for rotating the wiper holding member about the rotation shaft; and a control unit for controlling the rotation mechanism, wherein the recording head includes a cleaning liquid supply region disposed on an upstream side in the wiping direction of the ink ejection region, the cleaning liquid supply region in which a plurality of cleaning liquid supply ports for supplying cleaning liquid are formed, the control unit is capable of performing a recovery operation of the recording head including a cleaning liquid supply operation for supplying the cleaning liquid from the cleaning liquid supply ports, and a wipe operation for wiping the ink ejection surface with the wiper in a state holding the cleaning liquid, by moving the wiper from a position on the wiping direction upstream side of the cleaning liquid supply region to a position on the wiping direction downstream side of the ink ejection region, and in the wipe operation, the control unit rotates the wiper holding member so that a pressure contact angle of a tip of the wiper to the ink ejection surface is decreased after the wiper passes the cleaning liquid supply region before reaching the ink ejection region.
