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.
