ABSTRACT:
A media spacing system for a fiber optic CRT printer. The system has a film coating over the fiber optic portion of the CRT, outside the phosphor display area, which keeps the media a fixed distance from the display area to provide for a uniform display of data on the media. The film may be applied in multiple layers, with each successive layer having a larger size, to create a rounded edge for the coating. A pressure plate is placed on the opposite side of the media from the film coating to keep the media firmly against the film coating. A compliant element, such as foam rubber, attaches the pressure plate to a fixed bracket to allow the pressure plate to adjust for bow and twist of the CRT, while maintaining pressure against the media.
