Result: By shopping this cheap shit (sorry, but I can not put it more positive) I put in a short time 140 euros in the sand and I can now buy a new printer!
I've had the Brother DCP-J315W. Strange is on, that you have to push relatively solid cartridges while such a small Plastikhüllenverschlüß is pressed. If the originals is not. No instructions included, just a strip must be deducted. Whether plastic wrap closure would have to be taken off, I do not know. Is nowhere. In one I pull it tried what does not work, even with a knife or other.
Just to avoid. I've had more than one printer, which I never had any problems and also I work in the IT sector. I am really not a "silly".
Conclusion
-----
Who wants to save with these cartridges, you should not buy!
