Abstract
A liquid ejecting apparatus, includes a main tank storing liquid, a liquid ejecting head ejecting the liquid toward a target, a liquid supply passage connecting the main tank with the liquid ejecting head for supplying the liquid, a subtank storing the liquid and supplying the liquid to the liquid ejecting head, and the subtank provided on the liquid supply passage, and a pressurizing unit supplying pressurized air to the liquid supply passage from the side of the main tank so that liquid in a liquid supply passage is evacuated to the subtank.
Claims25
A liquid ejecting apparatus, comprising:
- a main tank, storing liquid;
- a liquid ejecting head, ejecting the liquid toward a target;
- a liquid supply passage, connecting the main tank with the liquid ejecting head for supplying the liquid;
- a subtank, storing the liquid and supplying the liquid to the liquid ejecting head, and the subtank provided on the liquid supply passage;
- and
- a pressurizing unit supplying pressurized air to the liquid supply passage so that liquid in the liquid supply passage is evacuated to the subtank.
An evacuation tank for evacuating liquid used in a liquid ejecting apparatus, said liquid ejecting apparatus comprising:
- a main tank configured to store liquid, a liquid ejecting head configured to eject liquid toward a target, a liquid supply passage configured to supply the liquid in the main tank to the liquid ejecting head, a subtank, provided on the liquid supply passage, configured to store the liquid on the liquid supply passage and supplying the liquid to the liquid ejecting head, and a pressurizing unit configured to supply pressurized air to the main tank:
- wherein the main tank is replaceable with the evacuation tank and is connected to the liquid supply passage;
- and
- wherein the pressurized air is supplied to the liquid supply passage through the evacuation tank so that liquid in the liquid supply passage is evacuated to the subtank.
A method of evacuating liquid of a liquid ejecting apparatus, comprising the steps of:
- storing liquid at a main tank;
- ejecting liquid toward a target at a liquid ejecting head;
- supplying the liquid in the main tank to the liquid ejecting head via a liquid supply passage;
- storing the liquid at a subtank and supplying the liquid to the liquid ejecting head from a subtank, wherein the subtank is provided on the liquid supply passage;
- and
- supplying pressurized air to the liquid supply passage so that liquid in the liquid supply passage is evacuated to the subtank.
