The inks are properly. Have a multifunction machine MX885 for two weeks. The black of mitgeliferten cartridges was 10 days already empty. You know that the only supplied max. are half-filled. I have only the black cartridge been replaced and everything runs fine, even if the remaining original cartridges. That means for me that the cartridges offered here are indistinguishable from the originals at a technical level, the printer also noted no difference. Unpack, use, print ... save money ... happy !!
