The image does not look the same as the original.
Make sure you have performed the calibration procedures and
selected the correct printer profile; see Chapter 2 for more
information.
Try different combinations of scanner settings.
Check that your software is correctly installed.
If you are importing an image file into your application
software, see if the file format is acceptable for your software.
Also check that the settings of your application and your image
match. See your application software manual.
A line of dots is always missing on the scanned image.
If this happens on your printed image, your printer or its print
head may have a problem or need cleaning; see your printer
manual.
If this happens on both your screen and printout, the scanner's
sensor may be malfunctioning. Consult your dealer.
Using halftoning, textured dot patterns appear in the image.
This is normal; see your scanner manual for examples of
halftoning.
The color on the video display seems different from that of the
original image.
Depending on your monitor, its resolution/color settings, and
your EPSON TWAIN settings, the screen colors may be
different from the original. This may be normal, especially if
the colors in the printed image more closely match the original.
