A fluid ejection device includes a fluid-ejection mechanism, a scanning carriage, and a service station. The fluid-ejection mechanism is capable of ejecting fluid onto media. The scanning carriage is that on which the fluid-ejection mechanism moves while ejecting fluid onto the media. The service station is that to which the fluid-ejection mechanism is movable by the scanning carriage, and that at which fluid aerosol from the fluid-ejection mechanism is extracted by a vacuum via an airflow path from the fluid-ejection mechanism temporarily fluidically coupled to the vacuum during servicing of the fluid-ejection mechanism.
