Abstract
A color ink jet printer including a print carriage movable along a carriage scan axis, a plurality of non-black color printing ink jet printheads supported by the print carriage and offset relative to each other so that their nozzle arrays are non-overlapping along the media scan axis, and a black printing ink jet printhead having a nozzle array that overlaps along the media axis with one of the nozzle arrays of the non-black color printing ink jet printheads, whereby as the carriage is scanned along the carriage scan axis the nozzle arrays of the non-black color printing ink jet printheads traverse non-overlapping print regions and the nozzle array of the black printing printhead traverses a print region that overlaps one of the non-overlapping print regions traversed by the nozzle arrays of the non-black color printing ink jet printheads.
