Abstract
A device and method for supplying ink to ink jet printer heads comprising first and second carriage portions non-rigidly coupled such that the two carriage portions are free to rotate independently about their guide rod axis, but are constrained to move together axially. The first carriage portion contains one or more ink jet cartridges supplied with ink via connecting tubes having self-sealing septum attached to corresponding ink outlets on the second carriage portion. The ink outlets on the second carriage portion preferably comprise valves with actuators. The actuators preferably act to secure the septum within the ink outlets, and are preferably disposed such that the valve is closed when the actuator is raised, and open when the actuator is lowered.
