Comments about Canon� CLI-8PM Magenta Ink Cartridge:
I understand very well that, in order to get great photo printing, you need to have cartridges like photo cyan and photo magenta. They do print really beautifully.
I don't understand two things, though. Why, if I'm only printing in black, does the photo magenta or photo cyan cartridge run out of ink -- ink that the printer isn't even using? Does it evaporate, and if so -- WHY????
Secondly, if I'm only printing a page in black, and the photo magenta cartridge or photo cyan cartridge is out of ink, why on earth will the printer refuse to print???
Taken together or separately, these two things drive me crazy.
