Abstract

In some examples, a fluid ejection die includes a plurality of nozzles arranged in a plurality of nozzle columns, the plurality of nozzle columns distributed across a width of the fluid ejection die in a staggered manner, wherein nozzles of each respective nozzle column of the plurality of nozzle columns are spaced apart along a length of the fluid ejection die, wherein the plurality of nozzle columns includes a first pair of neighboring nozzle columns that are spaced by a first distance across the width. The plurality of nozzle columns includes a second pair of neighboring nozzle columns that are spaced by a second distance across the width, the second distance being larger than the first distance.

First claim

The invention claimed is:

1. A fluid ejection die comprising:
a plurality of nozzles arranged in a plurality of nozzle columns, the plurality of nozzle columns distributed across a width of the fluid ejection die in a staggered manner,
wherein nozzles of each respective nozzle column of the plurality of nozzle columns are spaced apart along a length of the fluid ejection die,
wherein the plurality of nozzle columns includes a first pair of neighboring nozzle columns, the neighboring nozzle columns spaced by a first distance across the width, and
wherein the plurality of nozzle columns includes a second pair of neighboring nozzle columns, the neighboring nozzle columns spaced by a second distance across the width, the second distance being larger than the first distance; and
an array of fluid feed holes including a respective first fluid feed hole and a respective second fluid feed hole fluidically coupled to each respective nozzle of the plurality of nozzles, wherein the respective first fluid feed hole and the respective second fluid feed hole are connected in parallel.

2. The fluid ejection die of claim 1 , wherein the plurality of nozzles includes a set of neighboring nozzles, wherein the neighboring nozzles of the set of neighboring nozzles are positioned across the width and have different positions along the length.

3. The fluid ejection die of claim 2 , wherein each nozzle of the set of neighboring nozzles is positioned in a different nozzle column of the plurality of nozzle columns.

4. The fluid ejection die of claim 2 , wherein the set of neighboring nozzles includes at least six neighboring nozzles.

5. The fluid ejection die of claim 1 , wherein the plurality of nozzle columns comprises at least three nozzle columns that are fluidically coupled therebetween.

6. The fluid ejection die of claim 1 , wherein each nozzle column of the plurality of nozzle columns comprises 50 to 200 nozzles.

7. The fluid ejection die of claim 1 , wherein the plurality of nozzle columns comprise at least eight nozzle columns that are fluidically coupled therebetween.

8. The fluid ejection die of claim 1 , wherein the respective first fluid feed hole and the respective second fluid feed hole are fluidically coupled to an ejection chamber of the respective nozzle.

9. The fluid ejection die of claim 8 , wherein the respective first fluid feed hole and the respective second fluid feed hole are to provide circulation of a fluid through the ejection chamber.

10. The fluid ejection die of claim 8 , wherein each nozzle column of the plurality of nozzle columns has less than 250 nozzles.

11. A fluid ejection die comprising:
a plurality of nozzles arranged in at least eight nozzle columns, the at least eight nozzle columns distributed across a width of the fluid ejection die in a staggered manner and being fluidically coupled therebetween, the plurality of nozzles arranged such that a set of at least eight neighboring nozzles of the plurality of nozzles includes a respective nozzle in each respective nozzle column of the at least eight nozzle columns,
wherein the at least eight nozzle columns include a first pair of neighboring nozzle columns that are spaced by a first distance across the width, and wherein the at least eight nozzle columns includes a second pair of neighboring nozzle columns that are spaced by a second distance across the width, the second distance being larger than the first distance.

12. The fluid ejection die of claim 11 , wherein the plurality of nozzles is a first plurality of nozzles, the at least eight nozzle columns is a first set of eight nozzle columns, and the fluid ejection die further comprises:
a second plurality of nozzles arranged in a second set of eight nozzle columns distributed across the width of the fluid ejection die in a staggered manner and fluidically coupled therebetween, the second plurality of nozzles arranged such that a set of eight neighboring nozzles of the second plurality of nozzles includes a respective nozzle in each respective nozzle column of the second set of eight nozzle columns.

13. The fluid ejection die of claim 11 , wherein each nozzle column of the at least eight nozzle columns comprises 50 to 200 nozzles.

14. The fluid ejection die of claim 11 , wherein each nozzle column of the at least eight nozzle columns has less than 250 nozzles.

15. The fluid ejection die of claim 11 , wherein the plurality of nozzles includes a set of neighboring nozzles, wherein the neighboring nozzles of the set of neighboring nozzles are positioned across the width and have different positions along a length of the fluid ejection die.

16. A method of forming a fluid ejection die, comprising:
arranging a plurality of nozzles in a plurality of nozzle columns, the plurality of nozzle columns distributed across a width of the fluid ejection die in a staggered manner,
wherein nozzles of each respective nozzle column of the plurality of nozzle columns are spaced apart along a length of the fluid ejection die,
wherein the plurality of nozzle columns includes a first pair of neighboring nozzle columns, the neighboring nozzle columns spaced by a first distance across the width, and
wherein the plurality of nozzle columns includes a second pair of neighboring nozzle columns, the neighboring nozzle columns spaced by a second distance across the width, the second distance being larger than the first distance; and
fluidically coupling an array of fluid feed holes to respective nozzles of the plurality of nozzles, the array of fluid feed holes including a respective first fluid feed hole and a respective second fluid feed hole fluidically coupled to each respective nozzle of the plurality of nozzles, wherein the respective first fluid feed hole and the respective second fluid feed hole are connected in parallel.

17. The method of claim 16 , comprising:
fluidically coupling the respective first fluid feed hole and the respective second fluid feed hole of the array of fluid feed holes to an ejection chamber of the respective nozzle of the plurality of nozzles.

18. The method of claim 17 , wherein the first fluid feed hole and the second fluid feed hole are to provide circulation of a fluid through the ejection chamber.

19. The method of claim 16 , wherein the plurality of nozzles includes a set of neighboring nozzles, the method comprising:
arranging the neighboring nozzles of the set of neighboring nozzles across the width and to have different positions along the length.

20. The method of claim 19 , wherein each nozzle of the set of neighboring nozzles is positioned in a different nozzle column of the plurality of nozzle columns.
