How to Avoid Problems

Here is some general advice on avoiding problems in your scanning jobs:
• Start with the best possible original image to scan.
• Select only the part of the image you want to scan. Preview the
image and select it with the Crop and Auto Crop buttons. Not only
does a more precise selection save file space, but your image
quality will be much higher.
• Check the output file size before beginning the scan. Make sure
you have enough room if you are scanning files that require a large
amount of disk space.
• Match your Color Mode to the output purpose. If you are scanning
text, use the Text Enhanced mode. If you are scanning line art, use
the Black and White setting, and so on.
• Match your scan resolution to the type of file you need. If you are
scanning images for use as .GIF or .JPG files on the Web, you do
not have to scan at 600 dpi. Although it is recommended that you
scan at a higher resolution than you need for high-quality color
images, you should balance that factor against your planned use
for the image.
• Take advantage of the Tone sheet features to enhance your images.

• Try to use TrueColor mode on your monitor so you can view your
preview image as accurately as possible.
