Abstract
A method of controlling a liquid droplet ejection apparatus includes: a pressure detecting step of detecting whether the pressure inside a functional liquid tank is below a lower-limit pressure of a working pressure or not; a step of confirming, when the pressure inside the functional liquid tank is below the lower-limit pressure, whether a functional liquid droplet ejection head is in imaging operation or not; and a pressurization control step of, upon confirmation that the functional liquid droplet ejection head is not in imaging operation, pressurizing the functional liquid tank to an upper-limit pressure of the working pressure.
