- If you cannot make copies as you want because of paper type, paper size, or paper capacity problems, use the recommended paper. See "Recommended Paper Sizes and Types", About This Machine.

- Using curled paper often causes misfeeds, soiled paper edges, or slipped positions while performing staple or 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 up side down. Also, lay paper on a flat surface to prevent paper from curling, and do not lean it against the wall.
