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 81.
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.
