Abstract: A sensor images drops ejected from a printhead nozzle. The sensor has two parallel spaced-apart rows of imaging pixels. In one example, a lens projects an image of a drop ejected from a printhead onto the rows sequentially as the drop travels along a trajectory.

Abstract: A color sensing apparatus includes an optical system that produces a spatially uniform light beam independent of the use of a diffusion chamber, and a color sensor that senses reflected light of a reflection of the spatially uniform light beam, wherein the optical system includes a light integrator with a tapered inlet surface and a lens secured to an exit plane thereof.
