Abstract
An ink tank and a print head are mounted on a carriage for supplying ink to an inkjet print. The ink tank includes: one or more ink chambers, where each of the ink chambers includes one or more functional elements (1) symmetrically arranged, mounted and centered about a center plane of the respective ink chamber, and (2) positioned perpendicular to a direction of movement of the carriage. The functional elements include, for example, a feed outlet for feeding ink to the print head, a supply inlet for supplying ink to the ink chamber, an ink movement damper, an ink level sensor, a vacuum inlet to extract air from the ink chamber, and a re-flow inlet to allow re-flow of air bubbles from the print head to the ink chamber.
