◦Make sure you have selected an OCR language that corresponds to the language used for the document you are scanning. For more information, see the documentation provided with the OCR program.

•Check the originals

When scanning from the scanner glass, the original must be loaded with the top facing the right edge of the scanner glass. Also, make sure the document is not skewed.
