Update 4/24/2015:
pity that I still have to give a negative message now, because as I wrote I had been with Hainsberger Cartridges never had problems and would use again without hesitation. When og Drum Kit is the case now after a few months, unfortunately, occurred, the device constantly "Drum Error" indicates (with a "drum life" of 94%) and only with great effort, the pressure of a few copies can be reactivated until the error message reappears. I happened to have the old original drum kit, this is inserted into the printer and then it goes back, though inevitably with poor quality and bands in print, because the drum kit is near the end). Because the original supply is functioning and the compatible not, I can unfortunately only put down to the compatible drum kit and not to another mistake of my printer.
