Abstract
A method and apparatus for increasing the efficiency of a vacuum-assisted, fuser entrance guide in a marking engine by varying the vacuum on the guide as a sheet of marking medium moves thereacross wherein a low vacuum is applied on the guide while the sheet of marking medium is being transported across the guide solely by the vacuum transport and is then increased once the lead edge of the sheet enters the nip between the fuser rollers and the sheet becomes driven by the more powerful force of the fuser rollers. The higher vacuum provides a greater attraction force on the sheet, which, in turn, prevents the trail edge of the sheet from sagging or drooping from the guide's surface.
