Abstract
A color ink jet printer including a print carriage movable along a carriage scan axis and a plurality of color producing 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, such that the nozzle arrays of the ink jet printheads traverse non-overlapping regions as the carriage is scanned along the carriage scan axis.
Claims10
A color ink jet printer comprising:
- a print carriage movable along a carriage scan axis;
- means for moving said print carriage along the carriage scan axis;
- means for moving print along a media scan axis that is substantially orthogonal to said carriage scan axis;
- and
- a plurality of non-black color producing ink jet printheads supported by said print carriage and having respective nozzle arrays for providing respectively different non-black color outputs, said non-black ink jet printheads being offset relative to each other by at least 2 units of the print resolution along the media scan axis so that their nozzle arrays are non-overlapping along the media scan axis;
- whereby the nozzle arrays of said non-black ink jet printheads traverse non-overlapping regions as said carriage is scanned along the carriage scan axis.
