摘要： A method of monitoring nozzle condition in an array of inkjet nozzles comprises ejecting at least one black ink drop from an inkjet nozzle, wherein the black ink comprises a black colorant and a colloidal metal or metal-containing dopant. Light from a collimated light source is directed onto an ink drop-in-flight, and light-scatter from the drop is detected. The dopant increases light-scatter by the ink drop of an incident collimated light beam relative to the same ink without the dopant. From the detected light-scatter, an operational condition of the inkjet nozzle is determined. The dopant is visually undetectable in a printed mark made by the black ink, and the ink has a printed black optical density which is substantially the same as that of the same ink without the dopant.

摘要： For each energy value of a number of energy values, the energy value is applied to cause a fluid-ejection nozzle to eject a fluid drop. After the energy value has been applied to the fluid-ejection nozzle, a velocity of the fluid drop is determined using a light-scattering drop detector of the fluid-ejection device. A turn-on-energy (TOE) for the fluid-ejection nozzle is determined based on at least the velocities of the fluid drops determined after applying the energy values to the fluid-ejection nozzle.
