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.

IPC: B01L3/00
Abstract: A fluidic die may include a at least one actuator, and fluid flow architecture to flow a first fluid through at least one fluidic channel, and flow a second fluid through the at least one fluidic channel to form a laminar flow between the first fluid and the actuator. The at least one actuator forms a drive bubble from the second fluid to cause the first fluid to be ejected from the fluidic die.

Abstract: Examples described herein include a printhead assembly that includes a housing having a printing material reservoir and a print nozzle array disposed in a side of the housing. The print nozzle array is coupled to the printing material reservoir through a first channel. The printhead assembly can also include a pressure equalization element disposed in the side of the housing and coupled to the printing material reservoir through a second channel to allow air to enter the printing material reservoir when a pressure in the printing material reservoir changes.

Abstract: In one example in accordance with the present disclosure a printer cartridge is described. The printer cartridge includes at least one backpressure chamber to provide backpressure to a fluid during deposition of the fluid onto a print medium. The printer cartridge also includes multiple fluid chambers in fluid communication with the at least one backpressure chamber. A fluid chamber provides fluid to a portion of a printhead. Adjacent fluid chambers are selectively in fluid communication with one another via valves.

Abstract: Printheads and methods of fabricating printheads are disclosed. An example printhead includes a substrate and a printhead die disposed on a surface of the substrate, where a top surface of the printhead die projects a first distance from the surface of the substrate. The example printhead also includes a barrier at least partially surrounding the printhead die. A top surface of the barrier projects a second distance from the surface of the substrate, where the first distance is less than the second distance.

Abstract: Controlling adhesives between substrates and carriers includes forming a depression into a bonding area of a backside surface of a substrate of a print head where the bonding area being formed proximate an ink feed slot formed through the thickness of the substrate from the backside surface to a front side surface; placing an adhesive between the bonding area and a substrate carrier, and moving the substrate and the substrate carrier together such that the adhesive flows into the depression.
