A method of making an ink cartridge by forming the ink cartridge with an ink chamber and an air accumulation chamber, forming a vent hole at a first end of the air accumulation chamber, and disposing a one way valve at the vent hole for preventing gas from entering the air accumulation chamber through the vent hole. A mass is placed within the air accumulation chamber, the mass having a dimension smaller than an interior dimension of the air accumulation chamber such that the mass is movable between the first end and a second end of the air accumulation chamber.
