Printhead assembly comprising wicking element

1. A printhead assembly comprising:

a printhead having an ink ejection face;

a wicking element positioned for receiving ink from an edge portion of said printhead and/or an edge portion of a pad being disengaged from said face, wherein said wicking element is positioned adjacent a longitudinal edge portion of said printhead; and,

print media guide mounted on a support, said guide having a guide surface for guiding print media past a printing zone adjacent said ink ejection face, wherein said wicking element extends into a cavity defined between said guide and said support.

2. The printhead assembly of claim 1 , wherein said wicking element comprises an absorbent material.

3. The printhead assembly of claim 1 , wherein said wicking element is substantially coextensive with said printhead.

4. The printhead assembly of claim 1 , wherein said printhead is wire-bonded along a longitudinal edge portion and said wicking element is positioned adjacent an opposite longitudinal edge portion.

5. The printhead assembly of claim 1 , further comprising a printhead maintenance station, said maintenance station comprising:

a pad having a contact surface for engagement with said ink ejection face.

6. The printhead assembly of claim 5 , wherein an edge portion of said pad extends beyond an edge of said printhead, such that at least part of said pad is in contact with said wicking element when said pad is engaged with said face.

7. The printhead assembly of claim 6 , wherein said edge portion of said pad is a final point of contact with said wicking element during disengagement.

8. The printhead assembly of claim 5 , further comprising:

an engagement mechanism for reciprocally moving said pad between a first position in which said contact surface is sealingly engaged with said face, and a second position in which said contact surface is disengaged from said face.

9. The printhead assembly of claim 8 , wherein said maintenance station is configured such that said contact surface is progressively contacted with said face during sealing engagement and peeled away from said face during disengagement.

10. The printhead assembly of claim 9 , wherein said peeling disengagement draws ink from said printhead towards said edge portion of said contact surface and/or said face.

11. The printhead assembly of claim 8 , wherein a peel zone between said contact surface and said ink ejection face advances and retreats transversely across said face during engagement and disengagement.

12. The printhead assembly of claim 8 , wherein said engagement mechanism moves said pad substantially perpendicularly with respect to said ink ejection face.

13. The printhead assembly of claim 8 , wherein said contact surface is sloped with respect to said ink ejection face such that, during disengagement, a first part of said surface is disengaged from said face prior to a second part, said second part comprising said edge portion.

14. The printhead assembly of claim 8 , wherein said pad is biased towards said first position.

15. The printhead assembly of claim 5 , wherein said pad is comprised of silicone, polyurethane, or a type of rubber.

16. The printhead assembly of claim 1 , wherein said printhead is an inkjet printhead.

17. The printhead assembly of claim 1 , wherein said printhead is a pagewidth printhead.
