Possible Cause
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.
Right and left sides of the document
to be scanned are not the same in
height, because of curling or
folding.
The document to be scanned was
loaded upside down.
The scanning glasses are dirty.
The scanning glasses are dirty.
The settings of the computer
monitor are wrong.
Depending on the documents
scanned, the color of documents
may not be scanned properly. For
example, the color of a highlighter
pen may be scanned lighter than it
appears.
The scanning glasses are dirty.
The scanning resolution settings,
combined with patterns within the
scanned image, may cause this
problem.
The motor speed control may cause
a louder noise when a short
document exits the unit. This
operation is normal.
11.1 Troubleshooting
Remedy
Adjust the document guides
properly to the size of the
document to be scanned. (page

Flatten the document (page 40)
and load it again after reducing the
number of sheets.
Load the documents with the
surface to be scanned facing up.
Clean the conveyor and scanning
glasses. (page 68)
Clean the conveyor and scanning
glasses. (page 68) If cleaning does
not improve the scanning density,
perform shading adjustment. (page
99)
Adjust the computer monitor
settings.
Setting the value for [Chroma]
higher in the scanning conditions
may solve this problem.
Clean the conveyor and scanning
glasses. (page 68)
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.
