The document guides are not
adjusted to the size of the
document to be scanned, or the
document to be scanned is set
slanted on the feed tray.
Adjust the document guides
properly to the size of the
document to be scanned. (page
28)
Right and left sides of the
document to be scanned are not
the same in height, because of
curling or folding.
Flatten the document (page 23)
and load it again after reducing
the number of sheets.
The image for a scanned

scanned, the color of documents
may not be scanned properly.

highlighter pen may be scanned
lighter than it appears.
Setting the value for [Chroma]
higher in the scanning conditions
may solve this problem.

There is noise or wave patterns
(moire pattern) on the scanned
image.
The scanning resolution settings,
combined with patterns within the
scanned image, may cause this
problem.
Change the scanning resolution
or turn the Moire Reduction
function on, and perform
scanning again. About Moire
Reduction function, refer to the
Image Capture Plus, TWAIN, or
ISIS help.
The sound made by paper being
ejected is higher than usual
