The first one was defective (the "smart" keyboard did not light up), but luckily the dealer (Prodimex in Geneva) exchanged in within 24h.

Scan quality is good, print too (although I haven't printed much).

But scanning is extremely slow (especially duplex) - like 1 page per minute!... and the accompanying software is disastrous. You can't even download it from Canon's website and lacks some basic features. I had the PIXMA MX 870 and was much happier with it.
