Print Quality Problems
The background is dark or dirty
White dots appear in the printout
Cause What to do
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 types” on page
366 for information on choosing paper.
The paper path inside the
printer may be dusty. Turn off the printer. Clean internal
printer components by printing three
pages with only one character per page.
