ABSTRACT:
An ink cartridge for an ink jet printing apparatus is disclosed. The ink cartridge includes an ink compartment and a filler compartment. The filler compartment has an absorbent filler and an ink expulsion outlet. The ink cartridge further includes a movable partition which largely separates the ink compartment from the filler compartment; however, the ink compartment freely supplies ink to the filler compartment for expulsion. The partition is biased toward the filler compartment to exert an even and continuous pressure against the filler. The applied pressure reduces waste and increases operational efficiencies and performance.
