So I'm guessing then that the answer to my question as to whether or not I can use card stock paper in my MG5620 printer is NO?
It would have seemed simpler to tell me directly that but at least now I know what paper it does take. Certainly wish I'd known the limitations before buying it! I like Canon but I would have bought a more expensive one if I'd known - doesn't seem like great marketing of their products.
Thanks for the info tho.
