INTEGRATED MULTI-COLOR INK JET PRINTHEAD

摘要

An integrated multi-color drop-on-demand type ink jet printhead (12). The printhead includes a main body portion (14) and a plurality of generally parallel, longitudinally extending ink-carrying channels (36) arranged into at least two channel arrays (35a-35d). A manifold (21a-21d) corresponding to each of the at least two channel arrays and in communication with each of the ink-carrying channels (36) of the corresponding array is formed in the main body portion (14). Ink is supplied to each of the at least two channel arrays from a corresponding ink source (18a-18d), each of which is filled with a different color of ink.
