Abstract
A mechanical key scheme is integrated into a composite pattern on both a print cartridge and its corresponding printer carriage chute. In a preferred embodiment the pattern incorporates a plurality of adjacent contiguous columns on both sides of a latch, with each column capable of defining multiple position bits in order to precisely differentiate between different types and/or different families of print cartridges.
