Even after you insert the first (! Black) cartridge I was surprised that the ink level indicator tells me that the cartridge is half empty already - a software error (that however does not itch my Epson which puts an end when the display to zero stands), or simply be because the cartridges are not filled correctly, in fact.
A test print and the next blast: the printed image is a disaster. Zigmaliges cleaning and adjusting then leads to an eternity to success. I can print a letter reasonably clean. The "happiness" but does not last long. Already a short time later - virtually at the second attempt - is even less. Some gray streaks decorate the paper. Since no more cleaning help. Many attempts and leaves later I give up. Those things are good probably nothing at all!
After all works surprisingly the color printout (also not original Epson cartridges, but not from this supplier) continue without any problems. Well, there's just today letters in dark blue. The recipient will be delighted by my creativity ...
Conclusion: I hope I have not messed with this (pardon) inferior cheap scrap the nozzle or the entire printhead. It can always freely decide whether to buy these cartridges - at least I no longer !!!
