摘要： Methods and apparatus are provided related to fluid dispensing heads. A dispense head is formed to define a plurality of fluid jetting nozzles and a surface pattern. The surface pattern is characterized by one or more voids extending inward from an outer surface of the dispense head. Fluid puddle formation during operation of the dispense head is limited in volume by way of the surface pattern. Fluid puddle limiting reduces or eliminates dispensing errors to an entity, undesirable artifacts from resulting on a printed media, or similar problems.

摘要： Methods for fabricating a printhead are described. In one embodiment, a method includes forming on a substrate using a single fabrication technique multiple resistors, some of the resistors to be used as heater resistors configured to eject fluid and some of the resistors to be used as storage resistors that store data, annealing the heater resistors, and intentionally not annealing at least one of the storage resistors, wherein the annealed storage resistors have a first state representing a first digital value and the unannealed storage resistors have a second state representing a second digital value, such that the values associated with the storage resistors can be read by an appropriate detection circuit.

摘要： A fluid ejection device includes a fluid chamber, a fluid restriction communicated with the fluid chamber, and a fluid channel communicated with the fluid restriction. The fluid restriction has a fluid restriction parameter defined as (2*W+2*H)*L/(H*W), wherein W is a width of the fluid restriction, H is a height of the fluid restriction, and L is a length of the fluid restriction. As such, the fluid restriction parameter is in a range of 1.5 to 5.75.
