As noted by another reviewer the multipack, this black cartridge is not functioning properly. When installing it is detected, and the level will be displayed. But then constantly put to the nozzle. It is more concerned with cleaning than with print and lucky when times really all nozzles are free, often after 4-5 cleanings. Which brings me to believe that the black pigment used for the Epson-nozzle is not good. Have now other foreign cartridges (HQ) tried, unfortunately not available on Amazon, and now he can finally show how good he actually print (I had really been concerned, the printer might have been a bad buy)!
