Scanned images of the following types of documents (characters) may not be recognized

- Documents with small characters scanned at a low resolution
- Skewed documents
- Documents written in languages other than the specified language
- Documents including texts written in italic characters
- Documents containing characters with superscripts/subscripts and complicated mathematical
expressions
- Documents with characters on an unevenly colored background
e.g. Shaded characters
- Documents with many decorated characters
e.g. Decorated characters (embossed/outlined)
- Documents with characters on a patterned background
e.g. Characters overlapping illustrations and diagrams
- Documents with many characters contacting underlines or borders
It may take extra time to perform text recognition on the following documents:
- Documents with complex layouts
- Documents with information other than text
e.g. Text on a shaded background

the [Scanning mode option] window. Clear the [Reduce bleed-through] checkbox.
