PRINTING SYSTEM HAVING PRINTHEAD BYPASS FROM CONTAINER
A printing system having a fluid container, a media width printhead having a first fluid port at one longitudinal end of the media width and a second fluid port at the other longitudinal end of the media width, a first fluid path interconnecting the container and the first fluid port of the printhead, a second fluid path interconnecting the container and the second fluid port of the printhead, a third fluid path interconnecting the first and second paths, wherein the first, second and third paths are configured so that fluid from the container flows between the first and second paths via the printhead and via the third fluid path.
1 . A printing system comprising:
a fluid container;
a media width printhead having a first fluid port at one longitudinal end of the media width and a second fluid port at the other longitudinal end of the media width;
a first fluid path interconnecting the container and the first fluid port of the printhead;
a second fluid path interconnecting the container and the second fluid port of the printhead;
a third fluid path interconnecting the first and second paths,
wherein the first, second and third paths are configured so that fluid from the container flows between the first and second paths via the printhead and via the third fluid path.
2 . A system according to claim 1 , further comprising a multi-path valve connecting the first path to the printhead and the third path.
3 . A system according to claim 2 , wherein the multi-path valve is operable to selectively provide fluid flow through the printhead and the third path.
