ABSTRACT:
An improved ink cartridge mounting system for a primary ink jet printer including an ink cartridge mounting element having four cartridge receiving openings, each specially configured to receive an ink cartridge containing ink of a particular color. A unique arrangement of six ribs extends from the outer periphery of each cartridge receiving opening to define a distinctive keying pattern adapted to seat an ink cartridge having a fluted end portion configured to mate with the distinctive keying pattern. The unique keying pattern designated for each different color are entirely complementary to a prior keying pattern employed for the same color in an alternate type of ink jet printer but for the provision of at least one additional rib. Thus, a cyan ink cartridge, for example, has a fluted end portion so configured to mate precisely with the cyan cartridge receiving opening of both the primary and alternative ink jet printers, while a cyan ink cartridge having a fluted end portion so configured to mate precisely with the cyan cartridge opening of the alternate ink jet printer will not seat in any opening of the primary ink jet printer.
