Unpacking, installing it! The exchange took place without problems, the new Partone was detected by the printer, the Brother HL-4140CN immediately. The printed image is indistinguishable from that of the original cartridge. Meanwhile, I have all the color cartridges replaced by Hans Berger. None of it had given some of the difficulties. Best quality at a great price, just great!
One thing is certain, the next cartridge is again by Hans Berger.
