Abstract
Ink is supplied to a supply tank from a second buffer tank, and ink is pressure-fed from the supply tank to a head. Further, ink is supplied from the second buffer tank to a recovery tank, and ink is pressure-fed from the recovery tank to the head. In both pressure-feedings, ink containing air bubbles within the head is recovered at a first buffer tank. The ink, that contains the air bubbles and is recovered at the first buffer tank, is sent to the second buffer tank via an ink flow path. A degassing section is provided on the ink flow path, and a degassing process is carried out while ink is being fed.
Claims2
A liquid ejecting device comprising:
- an ejecting head including a liquid chamber configured to store a liquid, and that ejects liquid that is within the liquid chamber;
- a first tank configured to temporarily store liquid that is to be supplied to the liquid chamber, and temporarily stores liquid that is recovered from the liquid chamber, and communicates with the liquid chamber;
- a second tank configured to temporarily store liquid that is to be supplied to the liquid chamber, and temporarily stores liquid that is recovered from the liquid chamber, and communicates with a portion of the liquid chamber which portion is different than a portion of the liquid chamber that is in communication with the first tank;
- a degas device degassing gas within recovered liquid;
- a first flow path communicating the first tank and the degas device, a first pump being provided within the first flow path;
- a second flow path communicating the second tank and the degas device, a second pump being provided within the second flow path;
- and
- a control section controlling the first pump and the second pump,
- wherein the control section, effects control such that liquid, that is degassed at the degas device, is supplied to the liquid chamber via the first flow path and the first tank, and liquid that is within the liquid chamber is recovered at the degas device via the second tank, and
- effects control such that liquid, that is degassed at the degas device, is supplied to the liquid chamber via the second flow path and the second tank, and liquid that is within the liquid chamber is recovered at the degas device via the first tank.
