table to unfocus the image slightly.
◗ Move or angle the document slightly.
◗ Adjust the Sharpness setting to a lower value to unfocus the image.
See Customizing Destination Settings
for more information.
◗ Change the Scale setting slightly.
◗ In the Image Type dialog box, make sure the Scanning Mode option
is set to Best and the De-screening option is set to On. See
