I own a the C3180 (which is a model similar to yours) and I have to say that it is an absolutely fantastic printer (easily the best I have owned).
I have owned it for as near as dam it to 2 years and I have had no problems whatsoever, even when I went to Vista.
I find the print quality to be absolutely fantastic. The scanning performance is the same.
