The first cartridge replacement of the original cartridges to compatible this MUST be changed immediately all cartridges. Then it works on the first try. I initially thought black alone would work - but since then came the error "cartridge not recognized". So all original parts out and completely replaced by new compatible - and already is everything fine!
The print is perfect. And by the way: with which you can also print photos. I'm sort of "technical" - and can not easily detect differences in quality.
I buy the parts to give it back!
