ABSTRACT:
An ink refill unit for replenishing an ink storage compartment of an inkjet printer is provided. The ink refill unit has a body containing a quantity of refilling ink configured to engage an interface of the storage compartment, and a plurality of actuators defined in the body for actuating a constrictor mechanism of the storage compartment as the ink refill unit engages the interface and deactivating the constrictor mechanism as the ink refill unit disengages the interface. The constrictor mechanism constricts a flexible tubular wall of the storage compartment by a predetermined amount.
