Abstract

When a printing head is filled with an ink, a circulating pump is controlled so that an ink equal to or greater than the entire volume of a circulating path circulates from a feeding path hole to a returning path hole via a printing head (in a forward direction), and after that, the circulating pump is controlled so that the ink equal to or greater than the entire volume of the circulating path circulates from the returning path hole to the feeding path hole via the printing head (in a reverse direction). By doing so, gas (bubbles) in the circulating path may be more securely discharged to a sub tank.
