A book scanned - then defective

To the go, to study, for example in hotels, I wanted to scan with the Fujitsu SV 600 many "thick reference books". So that I no longer have to carry around with me. The unit was sent from Amazon quickly in optimal packaging and made a very valued and 'heavy' feeling. The software installation worked right away. The "Scan Manager software" and so I now mean the user is, in my view, antiquated underground - as offer some scanner for 50 a better service. I therefore manual adjustment could not be found, I just started and am "driven automatic". And it was great! A 500-page tome was finished within 30 minutes. The scanner has scanned each case a DIN A3 page, although the open book has not even reached the DINA4 format. This is probably due to the lack of manual setting. Was not a problem: Within a second, the unit has not only cut away the edges but also partly my fingers when I have for example retained a page, so they do not Page Turner from alone. Furthermore, the waves and curves were successfully corrected. There were few places that were still distorted after the automatic correction and in some areas of the text was pale, but all within the acceptable range. The device detects relative zuverlaääsig by itself when one has turned over - you just need at the beginning of the scan button for about 3 seconds and hold.. I was very happy! Abder then the next morning, I immediately wanted to move on. The first 3 pages good result as before - can be seen on the PC screen for about 1 second, the 'original recording' (with tabletop, with fingers and curved sides) and then preview the finished corrected image. At page 4 then the uncorrected original was taken. Only Siete 14 and 15 were then corrected again and then again not, etc. The manual is only explains cryptically how to make a subsequent manual correction of a single page. In the FAQ (only in English) I can not find anything about it. Of course I did Handle multiple tests with off and shutdown, etc. Softwareneuinstallation. Always with the same result: Some pages are automatically corrected, most others do not. My Rating: List = 5 stars; Hardware = 4 stars; Software = minus 8 star. The unit returns.
