In the age old tradition, we bought new ink for our 6 year old Canon and the next week the printer died. The ink isn't Canon brand, but it's new and unopened and there are several cartridges of it.
Black is PGI525
Colours are CLI526 (B,C,M, or Y)
Does anyone's printer use these? I don't want anything for them other than the price of shipping to you, about £5, but I'd really prefer not to put them in a landfill.
