The edges of the document are
not scanned.
Check the position of your
source document. Adjust your
document's position so that the
image is within the glass area.
The document table has
non-readable areas around the
edges. If part of your document
extends beyond the maximum
limits marked on the document
table edge guides, you may have
to reposition your document so
that the image you want to scan
is within the readable area.
Make sure the marquee (the
frame showing the selected area)
has selected the entire image.
Your image is too dark.
Make sure your software
settings are correct for your
document type.
Try adjusting the brightness
with your application software.
Also check the brightness and
contrast values of your display
screen.
