Guidelines for using paper
For best results, use high-quality paper that is between 70 and
150g/m
2 (20-lb bond). 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.
Some light-weight or poor-quality papers may cause print quality
problems, jamming, or damage to the printer.

adhesion. Problems with
feeding. Too moist, too rough, too
smooth, or embossed; faulty
