Document Type

When recognizing typewritten texts or faxes, OCR quality can be improved by selecting the corresponding Document type in the Options dialog box.

For most documents, the program will detect the print type automatically. For automatic print type detection, the Auto option must be selected under Document type in the Options dialog box (the Tools>Options…> menu, then the Document tab). You can process the document in full-color or black-and-white mode.

You may also choose to manually select the print type as needed.

Tip. After recognizing typewritten texts and faxes, be sure to select Auto to process regular printed documents.
