Morning All, I have HP Photosmart 7520 which takes cartridge 364 & 364XL. My previous printer also used these cartridges so the change was seemless until today when installing a new black cartridge. My printer now tells me I have installed an older generation cartridge which is incompatible!!!!! yet it is a 364XL bought a few months ago.
Is there a solution to this problem apart from wasting a brand new cartridge and having to purchase another one please.
Thanks Happy_fella
