Abstract

Devices include one or more inkjet printheads, a reusable jetting sheet that is adjacent to nozzles of the printheads, support structures (e.g., drive rollers) contacting the sheet, and a cleaning station contacting the sheet. The reusable jetting sheet includes an opening, that is at least as large as the sets of nozzles, and a jetting area spaced from the opening. The support structures are adapted to move the reusable jetting sheet relative to the sets of nozzles. The inkjet printheads are adapted to eject ink from at least some of the nozzles, through the opening, to print media when the opening is positioned adjacent to the sets of nozzles, to print on print media. The inkjet printhead is further adapted to eject ink from at least some of the nozzles to the jetting area when the jetting area is positioned adjacent to the sets of nozzles to perform maintenance jetting.

First claim

What is claimed is:

1. An apparatus comprising:
an inkjet printhead having a set of nozzles;
a reusable jetting sheet adjacent to the set of nozzles;
support structures contacting the reusable jetting sheet; and
a cleaning roller contacting the reusable jetting sheet,
wherein the reusable jetting sheet comprises:
an opening at least as large as the set of nozzles; and
a jetting area spaced from the opening,

wherein the support structures are adapted to move the reusable jetting sheet relative to the set of nozzles,
wherein the inkjet printhead is adapted to eject ink from ones of the set of nozzles, through the opening, to print media when the opening is positioned adjacent to the set of nozzles,
wherein the inkjet printhead is adapted to eject ink from ones of the set of nozzles to the jetting area when the jetting area is positioned adjacent to the set of nozzles, and
wherein the cleaning roller is positioned, relative to the reusable jetting sheet and the set of nozzles, to contact the jetting area when the opening is adjacent to the set of nozzles.

2. The apparatus according to claim 1 , wherein the cleaning roller is positioned to remove jetted ink from the jetting area.

3. The apparatus according to claim 1 , further comprising a container adjacent to the cleaning roller, wherein at least a portion of the cleaning roller is positioned within the container, and wherein the container is adapted to maintain cleaning fluid in contact with the cleaning roller.

4. The apparatus according to claim 1 , wherein the support structures comprise drive rollers adapted to rotate to wind and unwind the reusable jetting sheet on and off the drive rollers to move the reusable jetting sheet relative to the set of nozzles.

5. The apparatus according to claim 1 , wherein the jetting area comprises an area of unbroken continuous surface of the reusable jetting sheet.

6. The apparatus according to claim 1 , wherein the reusable jetting sheet comprises a flexible material.

7. The apparatus according to claim 1 , wherein the inkjet printhead comprises a plurality of inkjet printheads, each having a set of nozzles, and wherein the opening is at least as large as an area occupied by all sets of nozzles.

8. An apparatus comprising:
an inkjet printhead having a set of nozzles;
a reusable jetting sheet adjacent to the set of nozzles;
support structures contacting the reusable jetting sheet; and
a cleaning station contacting the reusable jetting sheet,
wherein the reusable jetting sheet comprises:
an opening at least as large as the set of nozzles; and
a jetting area spaced from the opening,

wherein the support structures are adapted to move the reusable jetting sheet relative to the set of nozzles,
wherein the inkjet printhead is adapted to eject ink from ones of the set of nozzles, through the opening, to print media when the opening is positioned adjacent to the set of nozzles, and
wherein the inkjet printhead is adapted to eject ink from ones of the set of nozzles to the jetting area when the jetting area is positioned adjacent to the set of nozzles, and
wherein the cleaning station is positioned, relative to the reusable jetting sheet and the set of nozzles, to contact and clean the jetting area when the opening is adjacent to the set of nozzles.

9. The apparatus according to claim 8 , wherein the cleaning station is positioned to remove jetted ink from the jetting area.

10. The apparatus according to claim 8 , wherein the cleaning station comprises a container adjacent to a cleaning roller, wherein at least a portion of the cleaning roller is positioned within the container, and wherein the container is adapted to maintain cleaning fluid in contact with the cleaning roller.

11. The apparatus according to claim 8 , wherein the support structures comprise drive rollers adapted to rotate to wind and unwind the reusable jetting sheet on and off the drive rollers to move the reusable jetting sheet relative to the set of nozzles.

12. The apparatus according to claim 8 , wherein the jetting area comprises an area of unbroken continuous surface of the reusable jetting sheet.

13. The apparatus according to claim 8 , wherein the reusable jetting sheet comprises a flexible material.

14. The apparatus according to claim 8 , wherein the inkjet printhead comprises a plurality of inkjet printheads, each having a set of nozzles, and wherein the opening is at least as large as an area occupied by all sets of nozzles.

15. A method comprising:
controlling, using a controller of a printing apparatus, support structures to move a reusable jetting sheet relative to a set of nozzles of an inkjet printhead of the printing apparatus to position an opening in the reusable jetting sheet adjacent to the set of nozzles;
controlling, using the controller, the inkjet printhead to eject ink from ones of the set of nozzles, through the opening, to print media to perform printing on the print media;
controlling, using the controller, the support structures to move the reusable jetting sheet relative to the set of nozzles to position a jetting area of the reusable jetting sheet adjacent to the set of nozzles;
controlling, using the controller, the inkjet printhead to eject ink from the set of nozzles to the jetting area to perform maintenance jetting from ones of the set of nozzles; and
controlling, using the controller, a cleaning roller to remove jetted ink from the jetting area when the controlling of the support structures simultaneously positions the opening adjacent to the set of nozzles and positions the jetting area adjacent to the cleaning roller.

16. The method according to claim 15 , further comprising controlling, using the controller, the cleaning roller to rotate within a container maintaining cleaning fluid when controlling the cleaning roller to remove the jetted ink from the jetting area.

17. The method according to claim 15 , wherein the controlling the support structures comprises rotating drive rollers to wind and unwind the reusable jetting sheet on and off the drive rollers to move the reusable jetting sheet relative to the set of nozzles.

18. The method according to claim 15 , wherein the jetting area comprises an area of unbroken continuous surface of the reusable jetting sheet.

19. The method according to claim 15 , wherein the reusable jetting sheet comprises a flexible material.
