Abstract
A replaceable ink supply module which provides replenishment of an inkjet printhead includes a collapsible bag, an enclosure box, a connective tube, and an on/off valve. These four components are incorporated into a composite sealed system which remains intact during shipment, storage, installation and operation. The collapsible bag is placed inside of the protective enclosure box and has an end-connect outlet permanently attached to one end of the connective tube. The other end of the connective tube carries a permanently attached on/off valve designed for periodic engagement with an inlet valve of an inkjet printhead.
