Using curled paper often causes misfeeds, soiled paper edges, or slipped positions while performing stack printing. When using curled paper, take the stiffness out of the paper with your hands to straighten out the curl, or load the paper upside down. Also, lay paper on a flat surface to prevent paper from curling, and do not lean it against the wall.
