I had the issue of an old toner running out, and when replacing it with a new one it still displayed the toner as empty. After resetting the toner as shown in the Video, the Printer prints again but no yellow (it was the yellow cartridge in my case) is being printed. The Yellow toner has a small line with no powder along its roller (exactly where the drum contacts the toner), so it seams like the toner ist no longer spinning after the manual reset.
