Quite sad to have to write what I am about to regarding this printer because underneath it all there's an absolutely first class printer just waiting to break out.
I purchased mine in July 2009. I was immediately impressed with the build quality, aesthetics and very impressed with the noise levels once I started printing. Setting it up was an absolute breeze and I was really excited to start printing. I started out with some Permajet FB Royal paper along with their ICC profiles for the printer/paper combination. Firstly, the black and whites are breathtaking, I mean absolutely stunning. Great contrasts, no metamerism in different light (no bronzing), no colour tints - just perfect (especially on the FB Royal paper). Unfortunately colour is a different story. All of the prints I got from this printer were over saturated in the yellows/oranges and there was most definitely a slight yellow cast when viewing under daylight.
After spending weeks updating drivers and working with Permajet directly they offered to create a custom profile for me. I sent them the test patches generated exactly how I was instructed to and they phoned me telling me they had never seen test patches that were so dark and with what they thought was a magenta cast. I contacted Canon support - firstly let me wish whomever is reading this the fortune that they never have to deal with Canon support in the UK. Absolutely the worst support system I've ever encountered but it would take the whole review just to go into the details. Anyway, after some 8 weeks (during which time I only ever managed to speak to the guy working my ticket THREE times) I decided to go back to the vendor and ask for a refund (and they graciously arranged it for me). I would like to say that Canon even admitted there was a yellow cast, slightly dark and over saturated oranges but seemed at a complete loss as to why.
I should probably state that I am using a (colour calibrated) Macbook Pro and I'm not massively convinced by the drivers for the Canon. I suspected a couple of times there was an issue with it double-colour managing, although I could never prove it. I did try the Snow Leopard drivers which were better drivers but now you can no longer make tweaks to the color options when using icc profiles (I used to compensate the colour cast by adding some blue and lightening the image to get an accurate result).
In short - I REALLY wanted to like this printer. I even toyed with buying another with the refund just in case on the off chance the one I had was faulty but I can't help feeling this is a trait of the printer/driver combination, at least on the Mac, and so I'm not going to risk it.
