Abstract
There is disclosed a method and apparatus for recovering an ink jet head having an opening communicating with a discharge port, the opening being provided on a same planar surface on which the discharge port for discharging ink is provided. An area of the opening is larger than an area of the discharge port. The method includes the steps of forcibly introducing gas into the ink jet head simultaneously through the discharge port and the opening, and exhausting the gas introduced into the ink jet head in the introducing step with ink through the discharge port. The gas introduced into the ink jet head enables the ink to be exhausted at an increased velocity in the exhausting step.
