I use the black cartridge now for almost a month. I was pleasantly surprised: The color and print quality were of the original cartridge in every way. Today, approximately one-third of the time that otherwise holds a black original XL cartridge arrived Printer Error Messages that had apparently nothing to do with the remaining ink level. After several unsuccessful attempts to reinstall the cartridge, it finally worked, but an uncertain feeling, how long they will print until the next error message or until complete failure remains.
