[QUOTE=nj2berlin;2449892]I am in Germany and purchased a Canon IP4600. I purchased ink tanks for the printer when I was back in the States. I bought the 220 and 221 ink tanks for the printer in America. When I tried to install them back in Germany the pop-up screen said i needed ink tanks 520 and 521. Is there a way to change the regional code so my printer recognizes the American ink tanks? Will it work if I change the regional code?[/QUOTE]
If you ever found a solution to this problem, please let us know. We have the exact opposite problem. We bought a Canon Pixma MX870 in New York and then moved to Berlin. We need 220 and 221 ink tanks and all we find here is 520 and 521.
