Abstract

A fluid ejection device includes a fluid ejection chamber having a drop ejecting element therein, a first fluid channel to communicate a first fluid with the fluid ejection chamber, a second fluid channel to communicate a second fluid different than the first fluid with the fluid ejection chamber, and a fluid pump communicated with one of the first fluid channel and the second fluid channel. As such, the fluid ejection chamber is to selectively eject drops of the first fluid, the second fluid, and a combination of the first fluid and the second fluid therefrom.
