A line of dots is always missing from the scanned

image.

❏ Print head malfunction is indicated when a line is missing on
printouts only. See your printer manual.
❏ Scanner sensor malfunction is indicated when a line is
missing on both screen images and printouts. Contact your
dealer.
When scanning printed matter, textured patterns
of dots appear inside particular areas of the
image.
This condition is normal. The scanner automatically minimizes
the problem if Image Type setting is Color Document or Black
& White Document in the Manual mode window.
Colors on your monitor are different from those in
the original image.
❏ Check the image settings of your scanner software, especially
data format (bits, pixel, color), gamma correction, and color
correction. Try different combinations of these settings.
❏ Check the color matching and color management capabilities
of your computer, display adapter, and software. Some
computers can change the color palette to adjust the colors on
your screen. See your software and hardware manuals for
details.
❏ Exact color matching is very difficult. Check your software
and monitor documentation for information on color
matching and calibration. Also see your Color Guide.
