After my color cartridge all came first, I had ordered this set. Delivery was very fast and the goods were packaged well. The color cartridge (works) is making excellent prints, no streaks or "false color". After a short time my black cartridge was all. After inserting my printer wanted to be calibrated (C4380). This he broke already when the print head back from the error message (display) cartridge not compatible. That was it. No chance to get him to accept the cartridge.
Unfortunately, also the seller has not reported after repeated EMail me.
