Summary: I had a big problem with black starter cartridge starting to splotch all over each print. Purchasing a third party OE cartridge (from Hi-Yield) resolved the issue, but I didn't get to even go below 100% on the first one that shipped with the printer. True PostScript Level 3 was the primary reason for buying and it is FAST with the Gigabit Ethernet.
Conclusion: I like the printer but, it is loud I have always respected Canon products for their quality but, the internal mechanics of this printer are not of Canon past ....and one of the worst manuals I've used in in my 25 plus years with computers.
Pros: High Quality Output, fast print speed
Cons: Difficult to use, Difficult Setup, loud, poor manual
Summary: Pros: fast printing after the first page; energy-saving (shuts down quickly); output doesn't stack neatly Cons: strong ozone smell; takes a long time to print the first page; VERY noisy; print quality is not bad, but not as good as HP
