HP7520 Ink cartridge imcompatible message

[curlyboy921]

I have a HP7520 printer bought from Hong Kong, the ink model I used to use was 564, but when I moved over to England, I couldn't find the 564, so I purchased the 364 as recommended by HP, but when I replaced the cartridges, it displayed an ink incompatible message.  I have reverted back to the 564 and the message has cleared.  How can I resolve this problem?
