Abstract
The invention provides a media sensor adjustment device for maintaining a media sensor in a preselected orientation with respect to print media prior to feeding the print media to a printing position within the printer. The adjustment device includes frame members, a media sensor housing attached to the frame members for holding a media sensor adjacent a media web and means for maintaining the sensor housing in a substantially fixed orientation relative to a media surface so as to maintain an optical surface of the media sensor substantially perpendicular to an optical path extending from the surface of the sensor to a plane defined by the media surface. The sensor adjustment device thus provides a highly reliable means for maintaining a media sensor in its critical optical perpendicularity at a predetermined distance so that reliable media identification can be obtained.
