Abstract

A system for supplying liquid ink to a thermal ink-jet printing apparatus comprises a housing defining a single chamber having a ventilation port and an outlet port. A medium occupies at least a portion of the chamber, the medium being adapted to retain a quantity of liquid ink. A scavenger member is disposed across the outlet port, providing a capillary force greater than that of the medium.
