Guidelines for using paper
For best results, make sure the paper is of good quality, and free of cuts, nicks, tears, spots,
loose particles, dust, wrinkles, voids, and curled or bent edges.
If you are unsure what type of paper you are loading (such as bond or recycled), check the
label on the package of paper.
For a complete list of supported media, see
