Troubleshooting
What to do
This printer is sensitive to moisture
absorbed by the paper. The higher the
moisture content in the paper, the
lighter the printout. Do not store paper
in a humid or damp environment.
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.
What to do
Remove the paper stack and fan it. Tap
it on a flat surface to even the edges.
Then reload the paper.
If the message appears on the LCD
panel or in the EPSON Status Monitor 3
window, it indicates that the amount of
toner is low. See "Toner cartridges" on
page 258 for information on replacing
the toner cartridges.
Replace the photoconductor unit. See
"Photoconductor unit" on page 263.
