Summary: Until today, I would have given this 5 stars. But today, just a week after the warranty expired, I turned the printer on and it was totally fried. (It's powered through an APC UPS.) The window showed Chinese characters, the computer didn't recognize it and called it unknown new hardware and the physical ink cartridge mechanism is locked up inside.
Summary: This printer failed after one week with Error 6800. Canon said they would send me a replacment (but it was a conditioned unit with a slightly marred scanner glass). Unbelievably, this second unit has now failed with the same Error 6800.
