A recovery system for a recording head according to the present disclosure includes a wiper, a drive mechanism, and a control portion. The control portion is able to execute a recovery operation for the recording head that includes an ink pushing-out operation that forcibly pushes out ink, a first wiping operation that moves the wiper in a first direction to wipe away purged ink, and a second wiping operation that moves the wiper in a direction opposite to the first direction to wipe away remaining ink. The wiper includes a first wiping surface disposed to face in the first direction, a second wiping surface disposed to face in a direction opposite to the first direction, and an upper surface. The first wiping surface and the upper surface have a high water repellency compared with the second wiping surface. |

1. A recovery system for a recording head that is provided with a nozzle region from which an ejecting nozzle for ejecting ink onto a recording medium is opened, comprising:
a wiper that wipes away purged ink which is forcibly pushed out from the ejecting nozzle, a drive mechanism that reciprocates the wiper along an ink ejecting surface including the nozzle region, and a control portion that controls pushing-out, ejection of the ink from the ejecting nozzle and operation of the drive mechanism, wherein the control portion is able to execute a recording head recovery operation that includes: an ink pushing-out operation that forcibly pushes out the ink from the ejecting nozzle and makes the purged ink adhere to the nozzle region; a first wiping operation that presses the wiper against a first position outside the nozzle region of the ink ejecting surface, thereafter, moves the wiper to the nozzle region in a first direction along the ink ejecting surface with the wiper pressed against the ink ejecting surface, thereby makes ink remaining on a tip end of the wiper adhere to the first position, wipes away the purged ink, and moves the wiper to a second position opposite to the first position with respect to the nozzle region; a leaving operation that after execution of the first wiping operation, makes the wiper leave the ink ejecting surface; and a second wiping operation that after execution of the leaving operation, presses the wiper against the ink ejecting surface, moves the wiper in a second direction opposite to the first direction along the ink ejecting surface with the wiper pressed against the ink ejecting surface and thereby wipes away the remaining ink, the wiper includes: a first wiping surface disposed to face in the first direction; a second wiping surface disposed to face in the second direction; and an upper surface disposed between the first wiping surface and the second wiping surface, and the first wiping surface and the upper surface have a high water repellency compared with the second wiping surface. |
