Abstract

A liquid ejecting apparatus includes a first liquid containing unit (pot 2) containing a liquid therein and a second detachable liquid containing unit (ink cartridge 3) containing a liquid therein and having a liquid containing volume smaller than that of the first liquid containing unit. A communication passage (5) communicates the first liquid containing unit with the second liquid containing unit. The first and second liquid containing units (pumps P1 and P2) are reciprocally replenished with the liquid by a liquid replenishing unit through the communication passage. When the liquid is replenished from the first or second liquid containing units to the other, a control unit (11) controls the liquid replenishing unit to replenish the liquid from the one liquid containing unit to the other liquid containing unit, until the liquid contained in the one liquid containing unit reaches a predetermined amount smaller than the liquid containing volume of the second liquid containing unit.

Description

Technical field [0001] The present invention relates to a liquid ejection device having a function of stirring liquid. Background technique [0002] As the ink used in a printer device such as a liquid ejecting device, an ink using a color component that is insoluble in a solvent or a color component that is difficult to dissolve is known. For example, in a pigment-based ink, where fine particles of the pigment as a color component are dispersed in a solvent such as water or petroleum-based solvents, the pigment may easily precipitate. For example, the specific gravity of a white pigment is about 4, and the specific gravity used for metallic pigments is about 2 to 3. In contrast, the specific gravity of the solvent is less than 1, and the difference between the specific gravity of the pigment and the solvent is 1 or more, so the pigment is easily separated from the solvent And precipitation. In addition, in the case of an ink using an insoluble or poorly soluble dye as a color ...
