I also noticed today after only printing 25 or so pages the large black ink tank is already showing it's only half full (half empty if you're a pessimist

None of the other tanks did this when installing and yes I'm an old pro with Canon ink tanks

The five ink tanks are never convenient (see picture)

It uses separate ink tanks for each color, which is good because if yellow runs out, you won't have to replace the entire cartridge

The PIXMA uses 5 ink tanks and comes with a full set of inks.

then you might want to spend a bit more $ for something more reliable and with larger ink tanks or a low price laser printer (which will give you smear proof, better resolution print at a lower overall price once you start adding up the replacement inks and things

Initial setup was easy, but one of the ink tanks dumped out all over my hand

Ink consumption is high on color photos and the black ink tank lasts an average amount of time

The printer uses 5 ink tanks and there is a larger black ink tank that is used for black and white documents

It has a really easy to read screen and you can get updates on how low your ink is getting

Color rendering is fairly accurate - print speed seems average to good and paper volume handling is limited as it is back loading and only holds so much
