Ink Cartridge Settings
Have you tried Canons FAQ? They suggest checking the grayscale box, which apparently only works with certain kinds of printing (duplexing and borderless will still use colors). I don't understand how colored inks are used to create black, but that's what they claim. Anyway, here's the link: http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=SupportDetailTabAct&fcategoryid=257&modelid=11641
all settings aere set to 1 sided but still prints 2 sided.
