Printer having pivotally capped duplexed printheads
View Patent ↗A printer is provided having pagewidth printheads for printing on opposite faces of print media, pagewidth cappers pivotally mounted to the printheads, and an actuating mechanism for pivoting the cappers between respective non-capping and capping positions relative to the printheads.
1. A printer comprising:
pagewidth printheads for printing on opposite faces of print media;
pagewidth cappers pivotally mounted to the printheads; and
an actuating mechanism for pivoting the cappers between respective non-capping and capping positions relative to the printheads so that the cappers are moved in an arcuate direction that is approximately normal to the printheads as the capping positions are approached.
2. A printer as claimed in claim 1 , wherein each capper is positioned in a confronting relationship to the respective printhead and is spaced from the printhead.
3. A printer as claimed in claim 1 , wherein each capper comprises a body portion, a lip portion formed from an elastomeric material peripherally configured to surround nozzles of the respective printhead in the respective capping position, and a cavity surrounded by the lip portion.
4. A printer according to claim 1 , wherein the pagewidth printheads are offset with respect to one another.
5. A printer according to claim 1 , wherein the actuating mechanism incorporates:
a first actuator arranged to move the printheads in an arcuate first direction from a first to a second position; and
a second actuator arranged to move the cappers in an arcuate second direction opposite to the first direction to effect capping of the respective printhead when the respective printhead is in the second position.
