Print quality is not aktzeptabel

Since then, the quality I becomes progressively worse with the new drum unit from the printer working. Lines seem to multiply on the roll and brought again to the paper for the next revolution. The unprinted part of the leaf is also no longer knows the whole print only lubricates and strokes draws on the entire sheet. The item is unusable and was disposed of together with the printer.

EDIT:
The service behind it is great! Exchange was offered (my fault that there is no longer the printer), and depending on which would certainly also works. There do seem (at least judging by the reviews) the great, overwhelming majority of the drum units to work as they should. Has my just only this did not and and do I rate.

If you buy I will give it enhanced Eight and the provider at any time reelect.
