| 摘要 | An apparatus includes a tank for holding a fluid for delivery to a printhead, the tank being open to the atmosphere. A manifold enables the fluid to flow from the tank to the printhead, a height of the manifold being lower than a level of the fluid in the tank when the fluid is flowing from the tank to the printhead. A siphon has a lower end of the siphon that is connectable to the manifold. An upper end of the siphon extends above the level of the fluid and is openable to the atmosphere. A height of a segment of the siphon between the upper end and the lower end is lower than the height of the manifold. | ||
