Tuning Brightness
ABBYY FineReader will display a warning message during scanning if the brightness setting is
incorrect. You may also need to adjust the brightness setting when scanning in black–and–white
mode.
To adjust the brightness:
1. Click the Scan button.
2. In the dialog box, specify the desired brightness.
Depending on which scanning interface is being used, either the ABBYY FineReader scanning dialog
box or the scanner driver dialog box will open. A medium value of around 50% should suffice in
most cases.
3. Proceed to scan the document.
If the resulting image contains too many "torn" or "glued" letters, troubleshoot using the table
below.

Window>Scale>Pixel–to–Pixel).
