Abstract
This prevents malfunctions caused by mixing of the liquid in the sub-tank and the liquid in the main tank. [Solution] When the printer's CPU determines that the first condition, that the quality of the ink in the sub-tank after the recovery step is below a predetermined quality, and the second condition, that mixing of the ink in the sub-tank and the ink in the cartridge occurs, is met (S52: YES), it executes a prevention step to prevent mixing of the ink in the sub-tank and the ink in the cartridge (S53, S55).
