Drop detector assembly and method |
摘要 |
A drop detector assembly includes an ejection element formed on a substrate to eject a fluid drop, and a light detector formed on the substrate to detect light scattered off of the fluid drop. A fluid drop ejected from a nozzle formed in a transparent nozzle plate scatters light that is detected through the transparent nozzle plate. |
