After delivery the cartridge arrived unsealed, but obviously open. Complaints were indeed processed by both seller and sent a new cartridge, which was, however, open as well as the first. Renewed complaint with the enlightening reply from the seller, the cartridge has been opened, to ensure that it is original and intact (!) - A joke at justification. It came, as it had to: Instead of the promised 3000 pages was the expression (the left edge of each blade = 10cm) are dipped after about 2000 pages weak and the cartridge had. This means 1/3 less coverage than specified. In the original each came out even more than the indicated 3000 pages, the type of printing is always pretty much the same with me, that is always similar coverage; So that can not have been the cause. I hope now that the next cartridge is better if no - never again.
