Hi,
It is not possible to turn off that message. Color printers need all the toners for checking at every power on the color registration and color density for making automatic adjustments.

My Versalink C505 shows "Empy yellow toner". That should be no proble for me since I obly need black in my printouts. Is it possible to turn off the error message "Yellow toner empty" and print with only black colour? It should be, it not realistic that I have to one empty toner (in this case the Yellow one) can stop the whole printer!
