Dear all, I was given from my daughter a printer HP PHOTOSMART 6520 that was purchased in the US some years ago. I'm from Germany/Europe. I have bought genuine HP cartridges of the 364 series through a local vendor, but they don't work on my printer (which only seems to accept 564 series). I get the error "cartridge incompatible" with the 364 cartridges, but I cannot get the 564 cartridges anywhere here in Europe. I have read that HP support can override the set-up of the printer, so that it can work with cartridges available in this region (see here: https://support.hp.com/us-en/document/c02558798). However, I have tried to contact HP support via the HP website but once I enter the product serial number, it simply says that my warranty is expired and no option is given to contact HP support. I am wondering if there is any other way I can get help? Thank you very much
Kind regards.
