Claims
- 1. 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 media along a media scan axis that is substantially orthogonal to said carriage scan axis; and
- a plurality of ink jet printheads supported by said print carriage in side-by-side sequential locations along the carriage scan axis and having respective nozzle arrays for providing respectively different color outputs, each of said nozzle arrays having a plurality of nozzles relatively positioned along said media scan axis at a same predetermined nozzle pitch for each of the printheads, said respective nozzle arrays being offset relative to each other along the media scan axis so that said respective nozzle arrays are non-overlapping along the media scan axis and are spaced apart along the media scan axis by at least 2 units of said predetermined nozzle pitch;
- whereby the respective nozzle arrays of said plurality of ink jet printheads traverse spaced apart non-overlapping print regions as said carriage is scanned along the carriage scan axis.
- 2. The color ink jet printer of claim 1 wherein said ink jet printheads comprise ink jet cartridges, and wherein said carriage includes respective support means for removably supporting each of said ink jet cartridges, said respective support means being substantially identical to each other and arranged side by side along the carriage scan axis and offset relative to each other along the media scan axis in accordance with offsets of the respective ink jet printheads relative to each other along the media scan axis.
- 3. The ink jet printer of claim 2 wherein said carriage has a width along the carriage scan axis, wherein each of said support means includes three walls and mounting flanges oriented orthogonally to an associated nozzle array, and wherein flanges of adjacent support means overlap so as to reduce the width of the carriage along the carriage scan axis.
- 4. 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 media along a media scan axis that is substantially orthogonal to said carriage scan axis;
- a plurality of ink jet printheads supported by said print carriage in side-by-side sequential locations along the carriage scan axis and having respective nozzle arrays for providing respectively different ink color outputs, each of said nozzle arrays having a plurality of nozzles relatively positioned along the media scan axis at a same predetermined nozzle pitch for each of the ink jet printheads, said respective nozzle arrays being offset relative to each other along the media scan axis so that their respective nozzle arrays are non-overlapping along the media scan axis and are spaced apart along the media scan axis by at least 2 units of said predetermined nozzle pitch; and
- another ink jet printhead supported by said print carriage side by side with said plurality of ink jet printheads and providing another different ink color output, said another ink jet printhead having a nozzle array at least partially aligned along the media scan axis with one of the nozzle arrays of said plurality of ink jet printheads;
- whereby the nozzle arrays of said plurality of ink jet printheads traverse spaced apart non-overlapping print regions as said carriage is scanned along the carriage scan axis.
- 5. The color ink jet printer of claim 4 wherein said plurality of ink jet printheads comprise a cyan printing ink jet printhead, a magenta printing ink jet printhead, and a yellow printing ink jet printhead, and wherein the nozzle array of said another ink jet printhead is at least partially aligned along the media scan axis with the nozzle array of the magenta printing ink jet printhead.
- 6. The color ink jet printer of claim 4 wherein said plurality of ink jet printheads comprise a cyan printing ink jet printhead, a magenta printing ink jet printhead, and a yellow printing ink jet printhead, and wherein the nozzle array of said another ink jet printhead is at least partially aligned along the media scan axis with the nozzle array of the cyan printing ink jet printhead.
- 7. The color ink jet printer of claim 4 wherein said plurality of ink jet printheads and said another ink jet printhead comprise substantially identically shaped ink jet cartridges, and wherein said carriage includes respective support means for removably supporting each of said ink jet cartridges, said respective support means being substantially identical to each other and arranged side by side along the carriage scan axis and offset relative to each other along the media scan axis in accordance with offsets of the respective ink jet printheads relative to each other along the media scan axis.
- 8. The color ink jet printer of claim 7 wherein said carriage has a width along the carriage scan axis, wherein each of said support means includes three walls and mounting flanges oriented orthogonally to an associated nozzle array, and wherein flanges of adjacent support means overlap so as to reduce the width of the carriage along the carriage scan axis.
