ABSTRACT:
An ink jet printing system for printing an image in the form of dots produced by ink droplets on a recording medium is provided. The present ink jet printing system is characterized by detecting the presence of air bubbles in the ink inside an ink chamber beyond a predetermined level and removing these air bubbles by pulling the air-ink boundary into the ink chamber thereby transferring the air bubbles to the air. The present ink jet printer allows to produce ink droplets of uniform characteristics since air bubbles are removed from the ink as soon as they are detected.
