- No program supplied with the instrument, while Canon come with a series of practical programs and very well done
- The driver is difficult to install (network, we must try several times to get anything other than a failure unexplained)
- The driver is slow and lousy pretext of being pretty
- THUNDERBIRD I use email client: the driver does not know this program. So I have no option "Scan To Mail".
- Technical support is nice but incompetent.
Apart from that, it works fine. But this is not the only one for this price ...
