Initially, the cartridge worked quite well, even if you could already see a difference with the original cartridges. For normal office use but perfectly adequate. Replacing the cartridges every time caused a huge mess in the original cartridges I make the change, however, not always without rumtrietscheln. After a few weeks, however, the printhead was unfortunately totally. The well lies not fix "Clean Intensive" by multiple "clean" and. After I had the printhead thoroughly flushed with alcohol, I was able to print a few times again, then everything was tight again. Since then, I again use "quality cartridges" My printer is running again 1a.
