If colors are patchy or distorted at the edges of the image . . .
If the document is thick or warped at the edges, the scan may appear discolored
from too much outside light. Try covering the edges of the document with paper
to block outside light.
If the document is not placed flat against the scanner, discoloration may appear in
the scanned image. Place the document flat and close the scanner cover.
If a line of dots is always missing from the scanned image . . .
If you are printing, your printer may be running out of ink or toner. For an
EPSON ink jet printer, try cleaning the print heads as described in your
documentation. If you are almost out of ink or toner, replace the cartridge.
If you see a missing line of dots on your screen as well as in printouts, your
scanner may be malfunctioning. Consult your dealer.
If a line of dots always appears in the scanned image . . .
Check to see if the docuement table is dusty or scratched. Clean the document table
glass as described on page 52.
If textured patterns of dots appear on areas of an image . . .
Use the quality setting instead of the speed setting and check the Descreening option
(when scanning from the Photo tab). The scanner will minimize the moiré patterns
that may appear.
If colors on your monitor or printed page are different from those in the original
image . . .
Increase your monitor's color palette to 16 bit or 24 bit.
Check to see if your application has adequate color matching and management
features, and if they are set up correctly.
Your monitor and printer use different technologies to represent colors, so the
printed colors may not match the colors you see on the screen.
