The toner cartridges were bought in stock to replace the original. As the first original was then empty, the replacement should serve it. So off the printer, the original expanded, unpacked the new and shaken (as recommended and practiced dozens of times already with others in the company), used properly, and started the printer. Since the black print was always only paler, the Troubleshooting went. Contact with the supplier was something schwiedrig since the purchase for more than a half a year ago, then and therefore no statement to the cartridges could be made more. Because the printer cartridge headed for only with an error message of the laser system during calibration, I asked for replacement. All cartridges (Black 0 prints the alleged mishandling by the printer, even after the firmware update; the other three ink cartridges original packing in Anlieferkarton yet) were sent back. Relatively quickly came after about ten days, the notification that me about 50% of the purchase price will be refunded. So I think, 50% for an article that could provide benefits 0 a handsome price. The quality seems and the Customer in ink in service D can because, unfortunately to be desired. Never again! Therefore, even a star.
