PLEASE HELP! I've had two Pixma MG7720's and both have gone out on me, so I purchased a Canon Pixma TR4527 on Ebay, lol and can't find cartridges anywhere. Probably because I thought they were 168A, but that is an error code, lol. Can someone please tell me what ink cartridges work for this model. I've searched everywhere and cannot locate the info. Appreciate the help 🙂
