To open the OCR Preferences dialog:

    2. Select OCR from the panel on the left of the preferences dialog to view or modify these preferences.

Settings

Recognition Languages - Options to set the default OCR language and ability to download new languages.

OCR Options - Options to automatically OCR when scanning

Image Processing - Settings used when passing the scanned image to the OCR engine to recognize text.

Note: From our testing, a resolution of 300 DPI produces good OCR results for most images. When dealing with scans containing noise, you may try using a lower DPI setting to get rid of the noise and obtain better OCR results.
