Since original toner are much more expensive than refilled, I bought the first time refilled toner. Are the set of 4 / were meanwhile 3 toner in use. After replacing the black toner, the printer reported as previously empty toner cartridge. I was with the refilled cartridges print about a hundred pages since then yet, but must always override the warning message. My guess: In her since the beginning was too little toner. Measured by the much lower price, not the promised, but acceptable. Destroying the experience with magneta was: When unpacking and tape stripping "brisk designated" it red color. Luckily I was able to remove them by means of cold washing off my pants. However, I've used the cassette - but only briefly. This incident alone is reason for me to buy only genuine toner. In the meantime, had to be replaced again magneta as empty. A cartridge works perfectly the way, another of the Set of 4 has not yet been required. Conclusion: If I had extremely save, I would try it again. However, I'd rather pay more if I do not have it resent.
