ABSTRACT:
This invention relates to the art of xerography and analogous graphic arts and more particularly to a copy sheet decurling mechanism employed in conjunction with a heat and pressure fuser for reducing or eliminating the curl induced into the copy sheets by the pressure roll of the fuser. To this end, means are provided for reverse (i.e. direction opposite to bending caused by the pressure roll) bending of the copy sheets while they are in a plastic state, that is while the sheets are still at an elevated temperature.
