Correction] or [Grain Correction] in the [Image Settings] section of the
Advanced Mode of ScanGear MP.
Note
If a print out of an image does not appear satisfactory or the same as what
you see on the monitor, you may need to change the machine’s settings,
or the machine itself may have engaged in problems.
Cause Action
Scan area was specified larger than
the original.
Specify the scan area appropriately.
If you click the Auto crop button of the ScanGear MP, the scan area is
adjusted automatically to match the size of the original. When scanning an
original surrounded by white borders such as a photo print, of if you
otherwise want to specify a custom scan area, specify the scan area
manually. Refer to the Scan Guide for details on manual scan area
specification.
