Print type
Documents may be printed using various devices such as typewriters and fax machines. OCR quality
may vary depending on how a document was printed. You can improve OCR quality by selecting the
correct print type in the Options dialog box.
For most documents, the program will detect their print type automatically. For automatic print type
detection, the Auto option must be selected in theDocument type group of options in the Options
dialog box (clickTools > Options...>OCR to access these options). You can process documents in full-
color or black-and-white mode.
You may also choose to manually select the print type as needed.

After recognizing typewritten texts or faxes, be sure to select Auto before processing regular printed
documents.
