Abstract

Examples include a fluid ejection die having a die length and a die width. The fluid ejection die may include a plurality of nozzles arranged along the die length and a die width. The plurality of nozzles is arranged such that at least one pair of neighboring nozzles are positioned at different die width positions along the width of the fluid ejection die. The example fluid ejection die further includes a plurality of ejection chambers including a respective ejection chamber fluidically coupled to each respective nozzle. The fluid ejection die further includes an array of fluid feed holes. The array of fluid feed holes includes at least one fluid feed hole fluidically each respective ejection chamber.

First claim

The invention claimed is:

1. A fluid ejection die having a die length and a die width, the fluid ejection die comprising:
a plurality of nozzles arranged along the die length and the die width, the plurality of nozzles comprising a set of neighboring nozzles, wherein the neighboring nozzles of the set of neighboring nozzles are positioned across the die width and have different positions along the die length, and wherein the plurality of nozzles comprise multiple columns of nozzles, wherein a distance between sequential nozzles of a first column of the multiple columns is within a range of 50 micrometers (μm) to 500 μm;
a plurality of ejection chambers including a respective ejection chamber fluidically coupled to a respective nozzle of the plurality of nozzles; and
an array of fluid feed holes including a fluid feed hole fluidically coupled to the respective ejection chamber.

2. The fluid ejection die of claim 1 , wherein the multiple columns comprise at least three columns that are fluidically coupled therebetween.

3. The fluid ejection die of claim 2 , wherein each column of the at least three nozzle columns comprises 50 to 200 nozzles.

4. The fluid ejection die of claim 1 , wherein the distance between the sequential nozzles of the first column is within a range of 100 μm to 400 μm.

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

6. The fluid ejection die of claim 1 , wherein the set of neighboring nozzles includes at least four nozzles, and each nozzle of the set of neighboring nozzles is positioned in a different column of the multiple columns.

7. The fluid ejection die of claim 6 , wherein the respective set of neighboring nozzles includes at least six neighboring nozzles.

8. The fluid ejection die of claim 1 , wherein each of the multiple columns has less than 250 nozzles.

9. The fluid ejection die of claim 1 , wherein a distance between the first column and a neighboring second column of the multiple columns is within a range of 100 μm to 400 μm.

10. The fluid ejection die of claim 1 , wherein the sequential nozzles of the first column are adjacent nozzles without any other nozzle between the adjacent nozzles.

11. The fluid ejection die of claim 1 , wherein the array of fluid feed holes includes a first fluid feed hole and a second fluid feed hole fluidically coupled to the respective ejection chamber, the first fluid feed hole and the second fluid feed hole to provide circulation of a fluid from a first fluid circulation channel through the first fluid feed hole and into the respective ejection chamber, and from the respective ejection chamber through the second fluid feed hole and out to a second fluid circulation channel.

12. The fluid ejection die of claim 11 , comprising a rib on a back surface of the fluid ejection die, the rib dividing the first fluid circulation channel from the second fluid circulation channel, wherein the plurality of nozzles are formed on a front surface of the fluid ejection die.

13. A fluid ejection die comprising:
a plurality of nozzles arranged in at least four nozzle columns, the at least four nozzle columns distributed across a width of the fluid ejection die, wherein sequential nozzles of a respective nozzle column of the at least four nozzle columns are spaced apart by at least 100 micrometers (μm), and wherein a first nozzle column of the at least four nozzle columns is spaced apart from a neighboring second nozzle column of the at least four nozzle columns by at least 100 μm; and
an array of fluid feed holes including a fluid feed hole fluidically coupled to a respective nozzle of the plurality of nozzles.

14. The fluid ejection die of claim 13 , wherein a of neighboring nozzles of the plurality of nozzles includes at least one nozzle in each respective nozzle column of the at least four nozzle columns.

15. The fluid ejection die of claim 13 , wherein the at least four nozzle columns comprise eight nozzle columns distributed across the width of the fluid ejection die in a staggered arrangement.

16. The fluid ejection die of claim 13 , wherein the sequential nozzles of the first nozzle column are adjacent nozzles without any other nozzle between the adjacent nozzles.

17. The fluid ejection die of claim 13 , wherein the array of fluid feed holes includes a first fluid feed hole and a second fluid feed hole fluidically coupled to an ejection chamber that is fluidically coupled to the respective nozzle, the first fluid feed hole and the second fluid feed hole to provide circulation of a fluid from a first fluid circulation channel through the first fluid feed hole and into the ejection chamber, and from the ejection chamber through the second fluid feed hole and out to a second fluid circulation channel.

18. 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 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 a distance between sequential nozzles of a first nozzle column of the at least eight nozzle columns is within a range of 50 micrometers (μm) to 500 μm.

19. The fluid ejection die of claim 18 , wherein a distance between the first nozzle column and a neighboring second nozzle column of the at least eight nozzle columns is within a range of 100 μm to 400 μm.

20. The fluid ejection die of claim 19 , wherein the distance between the sequential nozzles of the first nozzle column is within a range of 100 μm to 400 μm.
