You will notice that the recognized text likely contains some errors and scrambled characters that correspond to the graphics in the scanned image. Now you can use Microsoft Word’s features to make corrections, delete the scrambled characters or to format the text, as required.
If you find that the recognized text contains too many errors, however, there is not much you can do about that You can try changing the preset setting for scanning, i.e. Black and white, Color, Black and white from color page or Grayscale (available from File menu -> Scan New Document) and then again perform OCR on your document. Running OCR with the most appropriate settings gives the optimal results to the ability of the software to perform OCR.
If you are still not satisfied with the quality of the recognized text after changing these settings, you may wish to try a number of other OCR solutions like Abbyy FineReader Pro. If you are a Mac user, find a list of Mac compatible OCR software here.
