Abstract

In certain heated fuser systems, such as those found in the Versatec@ 8836 Laser Plotter and the Xerox @ 2510 and 2520 Engineering Copiers, media is forced against a heated fuser roll by a pressure element. A side view of such a heated fuser system is shown generally in the Figure, where during the fusing process, the imaged side of media 4 is forced against fuser roll 6 by the lower end of the pressure element, resilient pressure blade 8. The media is guided into the fuser nip by sling assembly 10, which also sup orts the lower end of

MOISTURE RELEASE HOLES FOR FUSER(Cont'd)

In certain heated fuser systems, such as those found in the Versatec@ 8836
Laser Plotter and the Xerox @ 2510 and 2520 Engineering Copiers, media is forced against a heated fuser roll by a pressure element. A side view of such a heated fuser system is shown generally in the Figure, where during the fusing process, the imaged side of media 4 is forced against fuser roll 6 by the lower end of the pressure element, resilient pressure blade 8. The media is guided into the fuser nip by sling assembly 10, which also sup orts the lower end of

form when media is fed beneath the pressure blade and the sling assembly. The moisture vapors formed during the fusing process condenses within the sling assembly and flow to to its edges and subsequently onto the media. Specifically, moisture vapors formed during fusing cause undesirable stains and deletions on imaged media. The formation of moisture vapors is particularly prevalent when translucent bond paper is fused since it has a higher moisture content than plain bond paper.

To avoid condensation of moisture in sling assembly 10 during fusing, two sets of holes in the assembly release moisture through air du...
