Since I had not yet not replace toner cartridge, I have of course omitted Product recession.
A few minutes ago it was then ..... but as far as the printer indicated that the black toner cartridge is near the end.
So I then replaced the black original cartridge with the black toner cartridge standing here to talk toner sets ..... and the DELL printer works as usual and there are also displayed on the Dell Software no error messages, ie, the printer accepts Toner cartridge as "original".
The 2 test sites I've just printed out, also do not see the printed image is different than before with the black original cartridge.
I'm happy and think (and hope) that the other colors are funktioneren as easily if their exchange is due.
