Claims20
A fluid ejection device, comprising:
- a series of spaced two-sided walls forming three channels therebetween, each of the three channels containing a drop ejector;
- and
- a fluid circulating element to circulate fluid across the drop ejector within each of the channels.
A fluid ejection device comprising:
- a first series of spaced walls comprising a first wall, a second wall and a third wall;
- a first drop ejector between the first wall and the second wall;
- a second drop ejector between the second wall and the third wall;
- a second series of spaced walls comprising a fourth wall, a fifth wall and a sixth wall;
- a third drop ejector between the fourth wall and the fifth wall;
- a fourth drop ejector between the fifth wall and the sixth wall,
- wherein the second series of spaced walls extends parallel to the first series of spaced walls and wherein the first series of spaced walls is staggered relative to the second series of spaced walls.
4 more elements
A method of operating a fluid ejection device, the method comprising:
- inducing fluid flow, with a fluid circulating element, along consecutive first ends of a series of at least three two-sided walls spaced by channels;
