Abstract

A drum cartridge with a plurality of heads for use with an ink-jet printer. This inventive cartridge increases the speed of printing and the resolution of the printed matter. The drum cartridge moves in a rotational fashion rather than in the typical reciprocating rectilinear fashion used by typical ink-jet cartridges.

Claims

1. An ink-jet printer, comprising:

means for loading a sheet of paper into said ink-jet printer;

rotating drum cartridge exhibiting a cylindrical shape, having a plurality of heads alternately located on a surface of said rotating drum cartridge forming a checkered pattern, having a rotation axis perpendicular to the direction of passage of said sheet of paper, and printing on said sheet of paper while moving exclusively in a rotary fashion about said rotation axis;

means for fixing an image onto said sheet of paper; and

means for ejecting said sheet of paper from said ink-jet printer.

2. The ink-jet printer of claim 1, further comprised of said head including a slot receiving printing material and orifices ejecting said printing material.

3. The ink-jet printer of claim 1, further comprised of said head having an outlet protruding from said surface of said rotating printing cartridge.

4. The ink-jet printer of claim 1, further comprised of said head including an outlet located on said surface and an inlet located on a different location from said outlet.

5. The ink-jet printer of claim 1, further comprised of a reservoir located into said rotating drum cartridge and connected to said head, containing recording material and supplying said recording material to said head.

6. The ink-jet printer of claim 1, further comprised of said rotating drum cartridge including a heating element.

7. The ink-jet printer of claim 1, further comprised of said plurality of heads having a length similar to both a width of said sheet of paper and a longitudial length of said rotating drum cartridge parallel to said rotation axis.

8. A rotating printing cartridge, comprising:

a shaft having a rotation axis perpendicular to the direction of passage of a sheet of paper; and

a plurality of heads alternately located on the surface of said rotating printing cartridge forming a checkered pattern printing on a sheet of paper while rotating about said rotation axis.

9. The rotating printing cartridge of claim 8, further comprised of said head including an inlet receiving recording material and an outlet outputting said recording material.

10. The rotating printing cartridge of claim 8, further comprised of said head including an outlet protruding from said surface of said rotating printing cartridge.

11. The rotating printing cartridge of claim 8, further comprised of said head including an outlet located on said surface and an inlet located on a different location from said outlet.

12. The rotating printing cartridge of claim 8, further comprised of a reservoir connected to said head, containing recording material and supplying said recording material to said head.

13. The rotating printing cartridge of claim 8, further comprised of said head including a heating element.

14. The rotating printing cartridge of claim 8, further comprised of a substrate layer between said head and a reservoir containing recording material.

15. The rotating printing cartridge of claim 8, further comprised of said plurality of heads having a length similar to both a width of said sheet of paper and a longitudinal length of said rotating printing cartridge parallel to said rotation axis.

16. A rotating printing cartridge, comprising:

a shaft having a rotation axis perpendicular to the direction of passage of a sheet of paper; and

a plurality of heads positioned on a surface of said rotating printing cartridge, each head including an inlet receiving printing material and an outlet having a different location from said inlet and outputting said printing material.

17. The rotating printing cartridge of claim 16, further comprised of said plurality of heads alternately located on a surface of said rotating printing cartridge forming a checkered pattern.

18. The rotating printing cartridge of claim 16, further comprised of a reservoir located on inside of said rotating printing cartridge containing recording material and supplying said recording material to said inlet of said head.

19. The rotating printing cartridge of claim 16, further comprised of said head including a heating element.

20. The rotating printing cartridge of claim 16, further comprised of said outlet protruding from said surface.

21. The rotating printing cartridge of claim 16, further comprised of said head including at least two orifices.

22. The rotating printing cartridge of claim 16, further comprised of said head including at least two heating element.

23. The rotating printing cartridge of claim 22, further comprised of said heating elements activated alternatively.

24. The rotating printing cartridge of claim 22, further comprised of said heating elements activated at the same time.

25. The rotating printing cartridge of claim 16, further comprised of a substrate layer between said head and a reservoir containing recording material.

26. The rotating printing cartridge of claim 16, further comprised of said plurality of heads having a length similar to both a width of said sheet of paper and a longitudinal length of said rotating printing cartridge parallel to said rotation axis.

27. An ink-jet printer, comprising:

means for loading a sheet of paper into said ink-jet printer;

a rotating drum cartridge exhibiting a cylindrical shape, having a chamber located on inside of said rotating drum cartridge and containing printing material, having a plurality of heads positioned on a surface of said rotating printing cartridge and connected to said chamber for receiving said printing material from said chamber, having a rotation axis perpendicular to the direction of passage of said sheet of paper, and printing on said sheet of paper while moving in a rotary fashion;

means for fixing an image onto said sheet of paper; and

means for ejecting said sheet of paper from said ink-jet printer.

28. The rotating printing cartridge, comprising:

a shaft having a rotation axis perpendicular to the direction of passage of a printing medium;

a chamber containing printing material; and

a plurality of heads alternately positioned on a surface of said rotating printing cartridge forming a checkered pattern, receiving said printing material and printing on said printing medium while rotating about said rotation axis.
