My HP Photosmart C4480 has fallen ill. It keeps complaining about my black cartridge being incompatible. I have bought a new cartridge and it is still moaning. Next step is phoning up HP right? (Google was not very helpful
)
Anybody else had any similar problems with a HP printer/possible solutions? And off the top of their heads, anyone know the standard warranty length?
Cheers for responses.
