After looking at the website of the manufacturer, I have for this scanner in the Decided assumption it would be one of the functions reasonably comparable software for Windows and Mac OSX in. At least with the ordered copy of me that was not so - the manufacturer hotline (competent, helpful and immediately accessible, this 5 star!) explained to me about the fact that the scanner is available in two versions with either Windows or were with Mac software. Unfortunately, I had as the main Mac users, the Windows Version caught. Well then: Windows XP (7 I have not tested) does it included software without hesitation - especially converting multipage documents in searchable PDFs (which not even be particularly great) works very decent and quick. And that is the crux when the scanner with the Mac version included software ExactScan LITE operates: that can indeed scan PDFs, but not create searchable! The text recognition remains here of around 90 euro expensive full version reserved! Mac users are So disadvantaged or have to pay extra for the same functions again; the practical "Scan Button" function remains Windows users reserved. Otherwise would have to notice that it is quite illusory, in my experience, 50 sheets of A4 nonstop durchzuscannen by direct debit - even despite previous "fanning" the leaves and uniform Paper quality, it comes around to multiple feed (mostly, but not always from the unit be recognized). The best experience I have done if I had not more than a maximum of 20 sheets lodged - but even then it is better to stand by and check whether some games slip through 2 parallel sheets - and then afterwards in the PDF is something missing. A completely unnecessary annoyance is the somewhat too short Paper support the output shaft - is allowed to run the scanner automatically, you may behind the templates from Floor collect. Clearly shorter paper sizes are common in the Far East ...? For the scan results and the Speed under Windows I forgive 5 star, due to the above details only three.
