Abstract

A capping mechanism is disclosed for a printhead (51) having a plurality of nozzles arranged to deliver ink onto print media which is transported past the printhead. The capping mechanism comprises actuating means (84, 85) arranged to move the printhead (51) in an arcuate direction away from a transport plane of the print media, from a printing first position to a capping second position, and a capping member (82) which is arranged to engage in nozzle capping engagement (57) with the printhead when the printhead is in the second position.

2. A printer comprising a) at least one printhead having a plurality of nozzles arranged to deliver ink onto print media which, in use, is transported past the printhead, and b) a capping mechanism having actuating means arranged to move the printhead in an arcuate direction away from a transport plane of the print media, from a printing first position to a capping second position, and a capping member which is arranged to engage in nozzle capping engagement with the printhead when the printhead is in the second position.
3. A capping mechanism for a pagewidth printhead assembly having-a) at least one pagewidth printhead and b) a plurality of nozzles located along the printhead and arranged in use to deliver ink onto print media as it is transported past the printhead;
the capping mechanism comprising-i) at least one capping member having a length corresponding substantially to that of the at least one printhead, and ii) actuating means arranged to move the at least one printhead in an arcuate direction away from the transport plane of the print media, from a printing first position to a second position at which the at least one capping member is engaged in nozzle capping engagement with the at least one printhead.
4. The capping mechanism as claimed in claim 3 wherein the at least one capping member is formed effectively as a one-piece member.
5. The capping mechanism as claimed in claim 3 wherein the at least one capping member comprises conjoined capping member portions having an aggregate length corresponding substantially to that of the printhead.
6. The capping mechanism as claimed in claim 3 wherein the at least one capping member comprises a body portion formed from a rigid material and a capping portion having a) an integrally formed elastomeric material lip portion and b) a cavity surrounded by the lip portion, and wherein the lip portion is peripherally configured to surround the nozzles collectively of the associated printhead.
7. The capping mechanism as claimed in claim 3 wherein the at least one capping member is arranged to be connected to a suction device whereby material may be sucked from the nozzle environment of the associated printhead.
8. The capping mechanism as claimed in claim 3 wherein a purging chamber is located within the at least one capping member and is arranged to be connected to a suction device whereby material may be sucked from the nozzle environment of the printhead.
9. The capping mechanism as claimed in claim 3 wherein a further actuating mechanism is provided to effect movement of the at least one capping member from a non-capping position to the second position.
10. The capping mechanism as claimed in claim 9 wherein the farther actuating mechanism is arranged to impart linear movement to the at least one capping member.
11. The capping mechanism as claimed in claim 9 wherein the further actuating mechanism is arranged to impart arcuate movement to the at least one capping member.
12. The capping mechanism as claimed in claim 10 wherein the at least one capping member is positioned in confronting relationship with an associated said printhead when the printhead is in the second position and wherein the further actuating mechanism is arranged to move the at least one capping member in a direction normal to the associated printhead when effecting linear movement of the at least one capping member from the non-capping position to the second position.
13. The capping mechanism as claimed in claim 10 wherein the at least one capping member is positioned adjacent to and laterally with respect to the at least one printhead, and wherein the further actuating mechanism is arranged to move the at least one capping member in a lateral direction to the second position.
14. A capping mechanism for a pagewidth printhead assembly having-a) two pagewidth printheads and b) a plurality nozzles located along each of the printheads and arranged in use to deliver ink onto print media as it is transported past the printheads;
the capping mechanism comprising-i) a capping member associated with each of the printheads and having a length corresponding substantially to that of the printheads, and ii) actuating means arranged to move each of the printheads in an arcuate direction away from the transport plane of the print media, from a printing first position to a second position at which the capping member is engaged in nozzle capping engagement with the associated printhead.
15. The capping mechanism as claimed in claim 14 wherein each capping member is formed effectively as a one-piece member.
16. The capping mechanism as claimed in claim 14 wherein each capping member comprises conjoined capping member portions having an aggregate length corresponding substantially to that of the printhead.
17. The capping mechanism as claimed in claim 14 wherein each capping member comprises a body portion formed from a rigid material and a capping portion having a) an integrally formed elastomeric material lip portion and b) a cavity surrounded by the lip portion, and wherein the lip portion is peripherally configured to surround the nozzles collectively.
18. The capping mechanism as claimed in claim 14 wherein each capping member is arranged to be connected to a suction device whereby material may be sucked from the nozzle environment of the associated printhead.
19. The capping mechanism as claimed in claim 14 wherein a purging chamber is located within each capping member and is arranged to be connected to a suction device whereby material may be sucked from the nozzle environment of the associated printhead.
20. The capping mechanism as claimed in claim 14 wherein a further actuating mechanism is provided to effect movement of each of the capping members from a non-capping position to the second position.
21. The capping mechanism as claimed in claim 20 wherein the further actuating mechanism is arranged to impart linear movement to each of the capping members.
22. The capping mechanism as claimed in claim 20 wherein the further actuating mechanism is arranged to impart arcuate movement to each of the capping members.
23. The capping mechanism as claimed in claim 21 wherein each of the capping members is positioned in confronting relationship with the associated said printhead when the printhead is in the second position and wherein the further actuating mechanism is arranged to move each of the capping members in a direction normal to the associated printhead when effecting linear movement of the capping members from the non-capping position to the second position.
