Is OK, but lubricates the beginning

The first prints can be forgotten. There is far too much of this black powder on it, so that all form black color blobs in the first 100 prints. But after that it behaves like a normal toner, as long as you use common paper (80gr / sqm). If thicker paper used (eg. 120 gr / sqm) immerse the black streaks on back. However, I must say I have not yet tested how the print result is when explicated in the pressure setting "thick paper" setting at this point.

In a nutshell: Not bad, but there are drawbacks. Who, like me, the printer introduced only for private use, the toner is completely ok.
