You may not be using the
correct type of paper for your
printer. If the surface of your paper is too rough,
printed characters may appear
distorted or broken. EPSON special
paper, or smooth, high-quality copier
paper is recommended for best results.
See “Available Paper” on page 18 for
information on choosing paper.
