The scanner works properly under Windows 7 64-bit, the drivers are automatically updated over the Internet. Due to the various setting Canon CanoScan LiDE 100 scanner options can achieve good to very good results in documents. Users, however, the scan from books, but consider the following.

Those who can not do without depth of field, should buy a CCD scanner. For my purposes, however, this scanner is perfect.
