Delivery carried out quickly and easily via the supplier ink pool. The toner was not detected right away, for us it was necessary in the meantime to use the old Original toner again. After now about 15 printed page are still about 6 cm long strip into the horizontal at a distance of 7.5 cm on the printouts. For me as a layman, the quality of the printouts is indistinguishable from the original toner.
