Patent abstract
In an inkjet device for containing, degassing and supplying ink, gas is supplied to a container for the ink so that the gas bubbles through the ink in the container. A controller controls a gas supplying means to operate in at least two modes including a degassing mode in which the pressure in the container is at a degassing pressure and the gas supplying means is controlled to supply the gas at a pressure above the degassing pressure to bubble through the ink, and an ink supplying mode in which the container is at an ink delivery pressure. In preferred examples, the ink container is arranged for supplying ink to a printhead; using the degassing arrangement, the formation of bubbles in the ink at the printhead can be reduced.
