We purchased our HP 7525 All-in-One printer in the U.S and then moved to Paris, France. When the original U.S ink ran out we followed the instructions on the HP web site on which ink cartridges to buy (364XL). When we installed them the printer reported that the new cartridges were not compatible with the printer. We called HP support and they reset the region codes for the printer by remote access to our computer. This took about an hour all said and done and there was no charge for this service, even though the printer itself was 3 months out of warranty. A few recommendations that seemed to help us through this process:

1) Use the HP web site to identify which cartridges are compatible in your new region.
2) Purchase the new cartridges before you call HP support, but don't install them.
3) Use the HP email support form to submit your support request before calling the HP support phone number.
4) Have a USB printer cable available since they will need that in order to perform the region reset, seems they can't use wireless networking to perform this support task.

Good luck!

HP print cartridges are now 'zoned' as stated above. You have to re-regionalize your printer, and this is done by typing in a code supplied by technical support, and can only be done 3 times in the life of the printer.

I have at last got this problem sorted unfortunately you will have to phone HP tech support as you need a code that the tech guy will give you but if you call 08443690369 chose option 2 in warranty it'll only cost 8p per minuet and just say you bought your product within the last 12 months they don't question it. Although I was still on the phone for 45 minuets.

HP Tech Support sorted this out for me - even though my printer is out of warranty I called the 0844 number (5p/min) and they helped.
The solution seemed printer-dependent since it involved generating a number based on my serial number, which was then entered into a secret dialog within the printer driver (Ctrl-double click the HP logo, bottom left corner in the "Printing preferences" driver dialog.)
My number was 0285 2652 5796 4163 9667 - wonder if that will work for you!?
Hope that helps
