Abstract:
An inkjet printing apparatus includes a print head, an ink tank containing ink to be supplied to the print head, a cap switchable between a covering position to cover a discharge port face and an exposing position to expose the discharge port face, a suction unit connected to the cap, and a control unit. The control unit controls the performing of an ink filling operation of filling the print head with the ink supplied from the ink tank. The ink filling operation includes a valve-closing suction operation of performing suction through the suction unit for a predetermined period of time while the cap is in the covering position. The apparatus further includes a detection unit configured to detect an ink filling state. The control unit controls the stopping of the ink filling operation in accordance with a detection result of the detection unit.

Claim (Index 10):
An inkjet printing apparatus comprising:\n a print head having a discharge port face in which a plurality of discharge ports that discharge ink are arranged; an ink tank containing the ink to be supplied to the print head; an ink supply path connecting the print head and the ink tank; a cap configured to be switchable between a covering position to cover the discharge port face and an exposing position to expose the discharge port face; a suction unit connected to the cap; a detection unit configured to detect an ink filling state in the ink supply path and the print head; and a control unit, wherein the control unit controls the performing of an ink filling operation of filling the print head with the ink supplied from the ink tank, the ink filling operation including a suction operation of performing suction through the suction unit for a predetermined period of time while the cap is in the covering position, and wherein the control unit controls the stopping of the ink filling operation in accordance with a detection result of the detection unit in the ink filling operation.
