Abstract: 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.

Abstract: A method and apparatus for imaging material. A section of a medium is photographed with a first camera having a first field of view. The medium is advanced along a feed direction and the section is photographed with a second camera having a second field of view. At least one of the first field of view and the second field of view is shifted from a nominal location by one or more reflective surfaces. An actual advance of the medium is compared with an intended advance of the medium and it is determined whether at least one of a media advance error and a dimensional change in the media exists in response to the comparing step.
