I have the OBV toner now ordered for the second time. On my first attempt, I ordered only the black toner. This was recognized immediately from my HP Color LaserJet CP1510n, but never found a clean print image. There were always visible on the leaf about 5 cm from the left edge small black spots. By now completely new toner kit I now reached a very very good print. All in all I am very satisfied. Very good packaging, light Tonerinitialisierung and top print image. All toner for under 100 - highly recommended.
