I bought this scanner knowing this was a refurbished item. Amazon delivered it on-time and as usual the service from Amazon was excellent. The scanner is another thing.First, the scanner was not locked as it should have been when I opened it. But that is not a big deal. The problem was that this scanner came with a bad lamp right out of the box! All scans had a bright yellow and red color in them (even white documents). The Canon customer service confirmed this and were ready to send another one. But I decided to return it to Amazon anyway.What struck me is that they promised it to be "FACTORY REFURBISHED" and they did not check such a basic thing as if it scans correctly or not. This makes me think that Canon just repacks them and takes a chance that it may be good. Decided to go with another brand and stick with brand new!Amazon quickly refunded the full amount. I give 5 stars to Amazon and 1 to Canon.
