Mixed feeling.

Now to use ...
I have the first cartridge (black) which have been recognized without any problems immediately and has printed correctly.
The next cartridge (Cyan) was also without any problems. This is then followed by the exchange of nächstenn two cartridges, magenta and yellow.
Thus went the chaos going on. The magenta cartridge ran out and everything was printed only red / pink.
I've done everything clean etc. and suddenly the cyan cartridge is not detected. After rumprobieren long garkeine more cartridge has been detected.

At one point I was so desperate that I have the other cartridges set used, try to 2x all cartridges were then recognized and prints properly again.
Slightly unnerving, but even if only one set of works, one is because even cheaper than original cartridges.
The quality is fine, I print mostly text, and it is enough for all time.
