Abstract

A capping mechanism is disclosed for a pagewidth printhead assembly having a pagewidth printhead (51) and a plurality of nozzles located along the printhead for delivering ink onto print media as it is transported past the printhead. The capping mechanism comprises a capping member (82) having a length corresponding substantially to that of the printhead (51) and an actuating mechanism (90) arranged to effect linear transitioning of the capping member (82) from a non-capping first position (fig. 9B) to a second position (fig. 9C) at which the capping member is located in nozzle capping engagement with the printhead.

2. The capping mechanism as claimed in claim 1 wherein the actuating means is arranged to effect linear transitioning of the at least one capping member from a non-capping first position to a second position at which the at least one capping member is located in nozzle capping engagement with the at least one printhead.
3. A capping mechanism for a pagewidth printhead assembly having-a) a 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) a capping member having a length corresponding substantially to that of the printhead, and ii) an actuating mechanism arranged to effect linear transitioning of the capping member from a non-capping first position to a second position at which the capping member is located in nozzle capping engagement with the printhead.
4. The capping mechanism as claimed in claim 3 wherein the capping member is formed effectively as a one-piece member.
5. The capping mechanism as claimed in claim 3 wherein the 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 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.
7. The capping mechanism as claimed in claim 3 wherein the capping member is arranged to be connected to a suction device whereby material may be sucked from the nozzle environment of the printhead.
8. The capping mechanism as claimed in claim 6 wherein a chamber is located within the capping member and is connected in fluid passage communication with the cavity and wherein the chamber 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 second actuating mechanism is provided for effecting movement of the printhead to the second position.
10. The capping mechanism as claimed in claim 9 wherein the second actuating mechanism is arranged to impart linear movement to the printhead.
11. The capping mechanism as claimed in claim 9 wherein the second actuating mechanism is arranged to impart arcuate movement to the printhead.
12. The capping mechanism as claimed in claim 3 wherein the capping member is positioned in confronting relationship with the printhead and wherein the actuating mechanism is arranged to move the capping member in a direction normal to the printhead when effecting linear transitioning of the capping member from the first to the second position.
13. A capping mechanism for a pagewidth printhead assembly having-a) two confronting pagewidth printheads and b) a plurality of nozzles 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 mechanisms arranged to effect linear transitioning of each of the capping members from a non-capping first position to a second position at which each said capping member is located in nozzle capping engagement with the associated printhead.

21. The capping mechanism as claimed in claim 19 wherein the capping members are positioned laterally with respect with the respective printheads when the printheads are in the second position and wherein the actuating mechanisms are arranged to move the respective capping members in a lateral direction when effecting linear transitioning of the capping members from the first to the second position.
22. The capping mechanism as claimed in claim 13 wherein a further actuating mechanism is provided for imparting linear movement to at least one of the printheads, wherein the capping members are positioned laterally with respect to the printheads when in the first position and wherein the capping members are moved laterally to a position between the printheads when transiting linearly from the first to the second position.
23. A capping mechanism for a pagewidth printhead assembly having-a) two offset pagewidth printheads and b) a plurality of 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 mechanisms arranged to effect linear relative transitioning of each of the associated capping members and printheads to a position at which the capping members is located in nozzle capping engagement with the associated printheads.
24.
