ABSTRACT:
An air removing device is connected to a tank to contain ink through a first supply tube, and an ink-jet head is connected to the air removing device through a second supply tube. The first supply tube and ink-jet head are heated and controlled. Air dissolved in ink is sucked out through a hollow fiber membrane provided in a housing by operating a vacuum pump by supplying ink to the hollow fiber membrane while heating and controlling atmosphere in the housing. Thus, air dissolved in ink is removed, and ink heated to a temperature suitable for ejection is supplied to the ink-jet head.
