The image you have scanned looks dirty.
1. If the image looks grainy, increase the scan resolution ( Software Guide).

magnification.

In ScanGear, click [Descreen] ( Software Guide).
4. Set the monitor display colors to 16-bit or higher.

White margins appear around the scanned image.
1. Specify the scan area.
In ScanGear, click [Multi-Photo Scan] to automatically specify the scan area.
If there are white margins around documents such as photographs, or if you want to trim a
document (i.e. you want to scan only one part of a document), specify the area of the scan manually
( Software Guide).

[Show scanner driver before scanning] ( Software Guide).

Even if you do not want to display ScanGear, you can make a scan at the paper size specified and
the area outside the paper size will not be scanned. Do the following:
On the Windows desktop, on the Toolbar, click [Settings]. In the Toolbar Settings dialog box, in the
tab for the button used to scan, specify the paper size ( Software Guide).
White lines appear on the left side of the image.
1. Place the document approximately 0.1 inches (3 mm) from the edge of the platen glass.
Cannot scan multiple photographs correctly.
1. Does the position of the photographs and the way they are positioned fulfil the following
requirements?
•There should be a gap of at least 0.4 inches (1 cm) between the edge of the platen glass and
photographs.
•There should be a gap of at least 0.4 inches (1 cm) between the edges of the photographs.
•There should be no more than ten photographs.
•The photographs should be straight (any tilting should be kept within 10 degrees).
2. Some applications do not accept multiple scans of more than two images.
Check the application’s documentation or contact the application’s manufacturer.
3. Clean the platen glass and document cover ( p. 11-1).
Scanned image is displayed at a large (small) size on the computer screen.
1. Enlarge or reduce the image display in the application.
However, if you open the image in Paint or Imaging, it may display at a large size and you will not be
able to reduce it. Open it in the MultiPASS Viewer.
2. Change the resolution in ScanGear and try scanning again.
The image will be large if resolution is high. It will be small if resolution is low ( Software Guide).
