I bought a pack of cli-8 ink tanks from Amazon, as my printer was among those listed for those tanks (pixma iP4000). However when I opened my printer, I saw the bci-6 ink tanks, and remembered that we have always bought those in the past. Does anyone know if the two types are interchangeable? Will the 8's work? What is the difference? I have not opened the box, thinking I might have to return them, so I have not examined them.
Thanks!
Thanks!
