摘要

MULTIPLE PRINT/CARTRIDGE INK JET PRINTER HAVING ACCURATE VERTICAL INTERPOSITIONING Ink jet printing apparatus of the type having feed means for advancing successive line portions of a print medium past a linear print zone includes a plurality of carriages constructed to traverse the print zone in a predetermined direction and removably support a plurality of print/cartridges. Each of the carriages includes referencing edges that are substantially parallel to the direction of the carriages traverse and indexing means for moving supported print/cartridges into a precise detent relation with respective referencing surfaces of their carriage unit.
