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 9):
An ink filling method for an inkjet printing apparatus including 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 on-off valve disposed in an ink passage between the print head and the ink tank, a cap covering the discharge port face, a suction unit connected to the cap, and a pressure measuring unit configured to measure a pressure at a predetermined position in the ink passage between the on-off valve and the suction unit, the method comprising:\n performing suction through the suction unit for a predetermined period of time while the on-off valve is in the closed position and the cap is covering the discharge port face and then opening the on-off valve; measuring a pressure variation per unit time through the pressure measuring unit, during the performance of suction, while the on-off valve is in the closed position; and changing, based on the measured pressure variation, suction time of the suction unit in next performance of suction.
