Scanning with an ADF | OmniWare Pro 12 ScanSoft manual

Brightness and contrast

Good brightness and contrast settings play an important role in OCR accuracy. Set these in the Scanner panel of the Options dialog box or in your scanner’s interface. The diagram illustrates an optimum brightness setting. After loading an image, check its appearance. If characters are thick and touching, lighten the brightness. If characters are thin and broken, darken it. Then rescan the page.

Scanning with an ADF

The best way to scan multi-page documents is with an Automatic Document Feeder (ADF). Simply load pages in the correct order into the ADF. Place blank pages if you want to save your document to multiple output files using the Create a new file at each blank page option. See “Saving recognition results” on page 79.

If you have a document longer than the capacity of your ADF, select Automatically prompt for more pages in the Process panel of the Options dialog box. Then a dialog box lets you add further page batches and signal when all pages are scanned.
