Patent ID: 7452053

Claim:
A fluid-ejection device comprising: a fluid-ejection mechanism capable of ejecting fluid onto media; a scanning carriage on which the fluid-ejection mechanism moves while ejecting fluid onto the media; and, a service station to which the fluid-ejection mechanism is movable by the scanning carriage and 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, wherein the service station comprises: a stationary chassis having a hole through a surface thereof leading to the vacuum; a retractable member slidably and sealably inserted within the hole of the surface of the stationary chassis, the retractable member defining the airflow path, the retractable member having a first position in which the retractable member is extended from the surface of the stationary chassis and a second position in which the retractable member is pushed downwards towards the surface of the stationary chassis; and, a movable service carriage receptive to the fluid-ejection mechanism as moved thereto by the scanning carriage, the movable service carriage movable over the stationary chassis and having a bottom surface from which a protruding portion thereof ends in a hole defining the airflow path, the protruding portion contactable with the retractable member to push the retractable member from the first position to the second position during servicing of the fluid-ejection mechanism.
