Abstract

See full text

A meeting surface between inks injected from the injection needles can be made closer to the filter by varying the timings of the ink injections from the plurality of injection needles, whereby larger pressure is applied to the filter. When pressure is applied which is larger than the ink holding force of the filter generated from the surface tension of the inks, the inks pass through the filter to fill space from an ink supply path to an ink path in a print head. In this manner, ink pressure on the filter can be appropriately controlled without increasing the amount of the ink from the injection needle above the filter. As a result, the inks pass through the filter to fill the ink path in the print head, and the inks can be prevented from leaking from ejection openings at the time of filling the inks.
