Since the quality of any particular brand or type of paper may be changed by the
manufacturer at any time, EPSON cannot guarantee the use of any particular
brand or type of paper. Always test samples of paper stock before purchasing
large quantities or printing large jobs.
Poor quality paper may reduce print quality and cause paper jams and other
problems. If you encounter problems, switch to a higher grade of paper. Do not
load curled or folded paper, envelopes, or transparencies.
