I have an HP Photosmart C4480 printer which was purchased in New Zealand (I used to live there). Now that I am living in the UK, I'm having trouble getting replacement print cartridges to work.
The cartridge numbers in NZ were 74 and 75. I've just purchased 350 and 351 as they list the C4480 on the box (74/75 not available in UK). However, I get "incompatible print cartridge" when using these. They're all genuine HP cartridges.
Is there something I need to do to reset the country the printer thinks it's in?
