❏
Check the color matching and color management capabilities of your computer, display
adapter, and software. Some computers can change the palette of colors on your
screen. See your software and hardware manuals for details.
❏
Windows:
Use the color management system for your computer, ICM. Add a color
profile that matches your monitor to improve on-screen color matching. Exact color
matching is very difficult. Check your software and monitor documentation for
information on color matching and calibration.
❏
Mac OS X:
Use the color management system for your computer, ColorSync. Exact
color matching is very difficult. Check your software and monitor documentation for
information on color matching and calibration.
❏
Printed colors can never exactly match the colors on your monitor because printers and
monitors use different color systems: monitors use RGB (red, green, and blue) and
printers typically use CMYK (cyan, magenta, yellow, and black).
Images are Rotated Incorrectly
❏
Make sure the documents or photos are placed on the document table correctly. See
“Placing Documents or Photos” on page 16 for instructions.
❏
If you are scanning using thumbnail previews, select the image and click the
rotation icon to rotate it. See “Previewing and Adjusting the Scan Area” on page 34
for instructions.
❏

Note:
❏
The Auto Photo Orientation feature will not work when you scan newspaper or magazine
pages, documents, illustrations, or line art. The feature will also not work when you scan
images that are 5.1 cm (2 inches) or smaller on any side.
❏
The Auto Photo Orientation feature may not work correctly if the faces in your image are
very small or not looking straight ahead, or if the faces are of infants. The feature may also
not work correctly if you scan an indoor image that contains no faces, an outdoor image in
which the sky is not at the top, or any image containing bright spots or objects in locations
other than the top of your image.
Uninstalling Your Scanning Software
You may need to uninstall and then reinstall your scanner software to solve certain
problems or if you upgrade your operating system.
