An ink-jet printing system includes a printer frame structure, and a carriage mounted on the printer frame structure for movement across a print zone during normal printing operations and which is positionable in a refill position. A printhead is mounted on the carriage, and has an inlet port accessible without having to remove the printhead. The printing system includes a support bracket attached to the printer frame structure, with an ink supply valve mounted on the support bracket. A clamp structure is mounted on the support bracket and is moveable between a clamping position for engaging the carriage in the refill position and securing the carriage, and a disengaged position wherein the clamp structure is not in contact with the carriage. An automated mechanism is operatively connected to the support bracket which moves the clamp structure from the disengaged position to the clamping position, and which moves the at least one ink supply valve toward the carriage in a rest position for engagement of the ink supply valve with the inlet port of the printhead mounted in the carriage. The automated mechanism includes a single motor which is activated to perform both functions, moving the clamp structure and the ink supply valve.
