Sorry for the confusion.
Without the toner cartridge, it says initializing, no motor noise, and quickly says insert black toner. As soon as the toner is inserted and the door closed, the same initializing appears, the motor runs for about 2 seconds and the same LED lights blink. So, the result is the same whether the toner is there when it is first turned on or whether it is inserted when the printer notices it is missing and then inserted.
Thanks.
