Printhead maintenance system comprising disposable sheet feed

1. A printhead maintenance system for maintaining a printhead in an operable condition, said maintenance system comprising:

(a) a printhead having an ink ejection face;

(b) an ink supply system comprising a face flooding system for flooding ink from said printhead onto said face;

(c) a sheet feed arrangement for feeding a disposable sheet past said printhead and through a maintenance zone spaced apart from said face; and

(d) a print media feed arrangement for feeding print media past said printhead and through a print zone,

wherein said maintenance zone is nearer said face than said print zone, and wherein no part of said disposable sheet makes contact with said printhead.

2. The maintenance system of claim 1 , wherein said printhead is a pagewidth inkjet printhead.

3. The maintenance system of claim 1 , wherein said face flooding system comprises a pressure system for positively pressurizing an ink reservoir or an ink conduit supplying ink to said printhead.

4. The maintenance system of claim 3 , wherein said pressure system comprises a control system for controlling an amount and/or a period of pressure applied to said ink reservoir or said ink conduit.

5. The maintenance system of claim 1 , wherein an ink conduit between an ink reservoir and said printhead comprises a valve for controlling an amount of ink flooded onto said face.

6. The maintenance system of claim 1 , wherein said sheet is a disposable sheet.

7. The maintenance system of claim 1 , wherein said sheet contacts flooded ink when moving past said face.

8. The maintenance system of claim 1 , wherein said flooded ink is wicked onto said sheet.

9. The maintenance system of claim 1 , wherein said sheet is a paper sheet.

10. The maintenance system of claim 1 , wherein said sheet has a high absorbency for absorbing said ink.

11. The maintenance system of claim 1 , wherein said sheet is different from said print media.

12. The maintenance system of claim 1 , wherein said maintenance zone is spaced less than 1 mm from said face.

13. The maintenance system of claim 1 , wherein a sealing member is positioned adjacent said printhead, such that at least part of said sheet, said face and said sealing member define a cavity when said sheet moves past said face.

14. The maintenance system of claim 1 , wherein said sheet feed arrangement comprises a sheet feed mechanism for automatically feeding said sheet through said maintenance zone.

15. The maintenance system of claim 1 , wherein said sheet feed arrangement is configured for manually feeding said sheet through said maintenance zone.

16. The maintenance system of claim 1 , wherein said sheet feed arrangement is configured to expel said disposable sheet from a printer comprising said maintenance system.
