Abstract:
1. A method comprising: moving media along a media path in a hard imaging device; at a first location along the media path, ejecting a plurality of droplets of a liquid marking agent in a direction towards the media to form a hard image using the media, the ejecting creating a plurality of aerosol droplets of the liquid marking agent; and at a second location along the media path downstream from the first location with respect to a direction of movement of the media along the media path, injecting a gas towards the media path to create a first boundary layer to impede movement of the aerosol droplets in a direction away from the media and to reduce an air speed at the first location to substantially null, the first boundary layer to reduce contamination of a component of the hard imaging device by the aerosol droplets compared with an absence of the injecting of the gas.
