Printer having capper for duplexed printheads
View Patent ↗A printer is provided having a pagewidth printhead assembly having opposed pagewidth printheads, a pagewidth capping member located adjacent the printheads, and an actuating mechanism arranged to move the printheads and capping member. Each printhead has a plurality of ink ejection nozzles arranged across the pagewidth to deliver ink onto opposite faces of print media as it is transported between the printheads. The actuating mechanism moves the printheads between respective printing positions and a non-printing position, and the capping member between the printheads in the non-printing position to cap the nozzles.
1. A printer comprising:
a pagewidth printhead assembly having opposed pagewidth printheads, each printhead having a plurality of ink ejection nozzles arranged across the pagewidth to deliver ink onto opposite faces of print media as it is transported between the printheads;
a pagewidth capping member located adjacent the printheads; and
an actuating mechanism arranged to move:
the printheads between respective printing positions and a non-printing position; and
the capping member between the printheads in the non-printing position to cap the nozzles.
2. A printer as claimed in claim 1 , wherein the actuating mechanism is arranged to move the capping member in a lateral direction relative to the printheads.
3. A printer as claimed in claim 1 , wherein the capping member has a capping portion for each of the printheads.
4. A printer as claimed in claim 3 , wherein the capping member comprises a body portion formed from a rigid material on which the capping portions are located, wherein each capping portion has an integrally formed elastomeric material lip portion and a cavity surrounded by the lip portion.
5. A printer as claimed in claim 4 , wherein the lip portions are peripherally configured to surround the nozzles collectively on the respective printheads.
6. A printer as claimed in claim 3 , wherein the capping member is formed effectively as a one-piece member.
7. A printer as claimed in claim 1 , wherein the printheads are disposed in a confronting, spaced-apart relationship when in the printing position.
8. A printer according to claim 1 , wherein the actuating mechanism is arranged to move the printheads in an arcuate direction between the respective positions.
9. A printer according to claim 1 , wherein the actuating mechanism is arranged to move the capping member in a direction normal to the printheads.
