Problem Solving
the correct color by adjusting
the marquee or frame border
and then adjusting the exposure.
See your electronic
Reference
Guide
for details.
The image on screen does not
look the same as the original or
when printed.
■
Because your monitor and
printer use different
technologies to represent colors,
your printed colors cannot
exactly match the colors you see
on your monitor screen.
■
Check your software settings
and make sure they are correct
for your image type. Try
different combinations of image
settings using your scanner
software.
■
Try increasing your monitor’s
color palette to 16 or 24 bit.
■
Your software may not have
sufficient color matching and
color management features, or
these components of your
software may not be correctly
installed. (See your software,
monitor, and computer manuals
for information on color
matching and calibration.)
■
If you are importing an image
file into your application
software, make sure the file
format is one your software can
read. Also check that the image
settings in your application are
appropriate for the type of
image you want to scan. (See
your software manual.)
Colors are patchy or distorted at
the edges of the image.
■
Make sure your document is
flat. If the document is very
thick or warped at the edges, the
edges of the image may be
discolored. Cover the edges of
the document with opaque
paper to block outside light.
■
If your document is too large,
part of the document extends
beyond the document table, and
that edge may not be in contact
with the document table.
Change the position of the
document.
A line of dots is always missing in
the scanned image.
■
If this happens in your printed
image only, your printer may be
low on ink or toner. Replace
your ink or toner cartridge. If
this does not solve the problem,
your printer may be
malfunctioning. (See your
printer manual.)
