ABSTRACT:
The ink-jet cartridge of the present invention includes two magnetic plates attached to the two sides of a flexible ink reservoir and facing each other with their sides of the same magnetic polarity. Alternatively, the two magnetic plates are attached to two flexible bags within the rigid ink reservoir and face each other with their sides of the same magnetic polarity. Due to the repulsive force generated by the two magnetic plates, a pressure regulating effect can be achieved within the ink reservoir to prevent ink leakage and provide smooth ink delivery while printing.
