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： A drop detection mechanism and method of use thereof is disclosed. In an embodiment, a shaped laser beam is employed to scatter light off of ink drops that are fired from a plurality of nozzles. A low cost, high throughput detector is utilized to detect the individual drops and thereby calculate the drop count, drop velocity and other drop characteristics. Consequently, through the use of the below described embodiments, new levels of print image quality are enabled on a broad range of inkjet printers, including industrial and web printers.
