ATTENTION
l When you select the [Set the marked text as a keyword for the PDF file] checkbox, it may take
extra time to process text recognition depending on your computer system environment.
l Scanned images of the following types of documents (characters) may not be recognized correctly.
In that case, better results in text recognition may be achieved by specifying a higher resolution in
[Image quality].
- Documents including handwritten characters
- 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
Example: Shaded characters
- Documents with many decorated characters
Example: Decorated characters (embossed/outlined)
- Documents with characters on a patterned background
Example: Characters overlapping illustrations and diagrams
- Documents with many characters contacting underlines or borders
l It may take extra time to perform text recognition on the following documents:
- Documents with complex layouts
- Documents with information other than text
Example: Text on a shaded background
l If bleed-through reduction is enabled, the recognition rate may be lowered as the marker may be
erased or lightened. In that case, disable it in the following procedure.
Select [Scan Button Settings] → [Scanning] tab → [Option] button from the Right-Click Menu to
show the [Scanning mode option] window. Clear the [Reduce bleed-through] checkbox (for SV600,
the [Reduce bleed-through] checkbox is located in the [Image quality] tab on the [Scanning mode
option] window).
l If the same character string is marked several times in the document, the same keyword is added
multiple times in the PDF file.
l Total length of all the keywords can be up to 255 characters, including punctuation marks in
between keywords.
l When you check keywords in Adobe Acrobat or Adobe Reader, the added keywords may be
displayed with a set of quotation marks (for example, "ABC").
