Nozzle arrangements and supply channels

A fluid ejection device comprising:

• a support structure having at least one fluid supply channel formed therethrough;
• and
• a plurality of fluid ejection dies, each respective fluid ejection die of the plurality comprising:
• a plurality of nozzles arranged in at least four nozzle columns along the die length and the die width in a staggered manner, each respective nozzle column of the at least four nozzle columns extending along the die length at a different die width position and being defined by nozzles aligned along the die length, nozzles of the plurality of nozzles arranged such that each respective nozzle of a respective set of four neighboring nozzles of the plurality of nozzles is arranged in a different respective nozzle column of the at least four nozzle columns and at a different die length position along the die length;
• an array of ribs that define an array of fluid circulation channels in the respective fluid ejection die, the array of fluid circulation channels fluidically coupled to the at least one fluid supply channel formed through the support structure;
• and
• each respective nozzle column including an array of fluid feed holes with both a respective first fluid feed hole and a respective second fluid feed hole fluidically coupled to each respective nozzle of the respective nozzle column such that each respective nozzle is fluidically coupled to respective first and second fluid feed holes, each respective first fluid feed hole of each respective nozzle column fluidically coupled to a common respective first fluid circulation channel of the array of fluid circulation channels, and each respective second fluid feed hole of the respective nozzle column fluidically coupled to a common respective second fluid circulation channel of the array of fluid circulation channels.

A fluid ejection device comprising:

• a support structure having a first fluid supply channel and a second fluid supply channel formed therethrough;
• and
• at least one fluid ejection die, each respective fluid ejection die of the at least one fluid ejection die comprising:
• a first plurality of nozzles arranged along a die length and a die width of the respective fluid ejection die, the first plurality of nozzles arranged in a first set of staggered nozzle columns such that neighboring nozzles of the first plurality of nozzles are positioned in different nozzle columns such that nozzles of the first plurality of nozzles zig-zag along the die length, the first plurality of nozzles fluidically coupled together, and the first plurality of nozzles fluidically coupled to the first fluid supply channel;
• and
• a second plurality of nozzles arranged along a die length and a die width of the respective fluid ejection die, the second plurality of nozzles arranged in a second set of staggered nozzle columns such that neighboring nozzles of the second plurality of nozzles are positioned in different nozzle columns such that nozzles of the second plurality of nozzles zig-zag along the die length, the second plurality of nozzles fluidically coupled together, and the second plurality of nozzles fluidically coupled to the second fluid supply channel.
