Malke, in this case, that's not quite correct. Windows Fax and Scan
(under Vista) doesn't appear to have an OCR capability. If he didn't
have Office 2007, then yes, he'd need some OCR software. But, according
to:
http://office.microsoft.com/en-us/help/HP010771031033.aspx
Microsoft Office Document Scanning (MODS) in Office 2007 does OCR on its
own. From what I can see, it looks like it's supposed to do OCR
automatically when it scans text documents.
C: I would have thought there'd be a "Document" setting under MODS. I
don't see one, though. It looks like the "Processing" tab under the
"Preset Options" item is the place to check. There's an OCR option
there. Either select and edit an existing preset or create a new one
and make sure that option is checked. Failing that, from within MODS,
you should be able to do an OCR conversion by clicking Tools | Recognize
Text Using OCR.
Also, and obviously (so I apologize if you've already checked), make
sure you're running Microsoft Office Document Scanning and not Windows
Fax and Scan.
