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

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 arranged such that at least one respective pair of neighboring nozzles are positioned at different die width positions along the width of the fluid ejection die; a plurality of ejection chambers including a respective ejection chamber fluidically coupled to each respective nozzle; and an array of fluid feed holes including at least one respective fluid feed hole fluidically coupled to each respective ejection chamber.

2 . The fluid ejection die of claim 1 , wherein the plurality of nozzles are arranged in at least three nozzle columns that are fluidically coupled therebetween.

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

4 . The fluid ejection die of claim 3 , wherein a distance between each nozzle of a respective nozzle column is within a range of approximately 100 μm to approximately 400 μm.

5 . The fluid ejection die of claim 2 , wherein a distance between each respective nozzle column of the at least three nozzle columns is within a range of approximately 100 μm to approximately 400 μm.

6 . The fluid ejection die of claim 1 , wherein the plurality of nozzles are arranged in at least eight nozzle columns that are fluidically coupled therebetween.

7 . The fluid ejection die of claim 1 , wherein the at least one respective pair of neighboring nozzles is a respective set of neighboring nozzles that includes at least four respective nozzles; and each respective nozzle of the respective set of neighboring nozzles is positioned in a different nozzle column.

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

9 . The fluid ejection die of claim 1 , wherein the nozzles are arranged in nozzle columns having less than 250 nozzles per nozzle column.

10 . The fluid ejection die of claim 9 , wherein the at least one respective fluid feed hole includes a respective first fluid feed hole and a respective second fluid feed hole fluidically coupled to the respective ejection chamber.

11 . 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, each respective nozzle of each respective nozzle column of the at least four nozzle columns being spaced apart along a length of the fluid ejection die, each respective nozzle of each respective nozzle column spaced apart at least approximately 100 μm, each respective nozzle column spaced apart at least approximately 100 μm; and an array of fluid feed holes including at least one respective fluid feed hole of the array of fluid feed holes fluidically coupled to each respective nozzle of the plurality of nozzles.

12 . The fluid ejection die of claim 11 , wherein a respective set 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.

13 . The fluid ejection die of claim 11 , wherein the at least four nozzle columns comprises eight nozzle columns distributed across a width of the fluid ejection die in a staggered arrangement.

14 . 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 at least one respective set of at least eight neighboring nozzles of the plurality of nozzles includes a respective nozzle of the respective set of at least eight neighboring nozzles in each respective nozzle column of the at least eight nozzle columns.

15 . The fluid ejection die of claim 14 , 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 at least one respective set of eight neighboring nozzles of the second plurality of nozzles includes a respective nozzle of the respective set of eight nozzles of the second plurality of nozzles in each respective nozzle column of the second set of eight nozzle columns.
