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.
• Parts of image missing or surrounded by extra white areas
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.
• Trouble scanning with Multi-Scan or Multi-Crop function
Cause Action
The original is positioned outside
the supported area.
Error arising from application
software specifications.
• Slow scanning speed
Check the position of the original on the document glass. Observe the
following when using the Multi-Scan or Multi-crop function.
• Keep more than 3/8 inch (10 mm) between the Originals, and the
Originals and the edge of the platen glass.
• A maximum of 10 originals can be scanned at once.
• If an original is slightly crooked on the platen-within 10 degrees of true-
the image is automatically straightened.
• The Multi-Scan function only works with rectangular originals such as
photos.
• Originals that are not rectangular (irregularly shaped, close-cropped
photos) cannot be detected correctly.
Some application softwares do not support multiple image scanning.
Scan each item individually without using the Multi-Scan or Multi-Crop
function.
