    摘要: A method of monitoring nozzle condition in an array of inkjet nozzles includes ejecting at least one black ink drop from an inkjet nozzle, wherein the black ink includes 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: An inkjet printhead includes an inkjet nozzle with a main actuator and at least one peripheral actuator in the same firing chamber. When the inkjet nozzle has sat idle, both the main actuator and the peripheral actuator are activated to jet at least one ink drop to renew the inkjet nozzle to mitigate decap conditions. When the inkjet nozzle has not sat idle, only the main actuator is activated to jet ink drops. The ink drops jetted by activating both the main and the peripheral actuators and the ink drops generated by activating only the main actuator have the same drop weight and drop velocity.

    摘要: In an embodiment, a fluid ejection device includes a die substrate having first and second fluid slots along opposite substrate sides and separated by a substrate central region. First and second internal columns of closed chambers are associated with the first and second slots, respectively, and the internal columns are separated by the central region. Fluidic channels extending across the central region fluidically couple closed chambers from the first internal column with closed chambers from the second internal column. Pump actuators in each closed chamber pump fluid through the channels from slot to slot.
