We love our Canon all-in-one but it uses a lot of ink. The one thing I really hate about the printer is it uses color ink even when we are only printing black and white or greyscale output. I would say we print 100 pages of black and white for every page of color but we go through color ink at about 1/4 the rate of the black ink.

I first purchased just the large black cheapo cartridges to try them out. Except for having to be careful about dripping ink during installation the black worked fine. So this time I've switched to using the color inks as well.

My wife recently asked me to print four 4 x 6 color photos for her, something we don't do often, and they came out great so the color cartridges work fine too.

My only concern is potential long term damage that could be done to the print heads due to possible inferior ink but time will tell. Using these Sophia cartridges is WAY less expensive than the Canon OEM cartridges.

I now have used both the black and color ink cartridges and they are working fine. The only problem is I have to be careful as there is a drop of liquid ink as I open the cartridge that can make a mess. As long as I am aware of that I can manage it.
