Abstract
Non-black ink jet printheads are arranged in a printer carriage such that the printhead nozzle arrays are non-overlapping in the carriage swath direction. A fixer printhead is positioned such that the print medium is first advanced past the fixer printhead prior to reaching any of the other printheads. The printheads are selectively driven during each direction of a bi-directional carriage movement, and the print medium is incrementally advanced before each change in carriage movement direction. The order of laying down droplets of different colors is the same during the movement in each direction, thereby eliminating bi-directional hue shifting print artifacts.
