MPC 5000 toner issue

[xman]

I have a remote client that has just emailed me saying that the machine displayed "Black Toner Empty ". They replaced the black toner and the machine no says " No Toner Black " and " Replace Toner Black ". They replaced the black toner again and still the same message. They are using genuine toner.

Please help.

here are the things to be checked toner pump, the tube and the toner clutch located at the back of Machine. we experienced this problem a lot and we always solved it by checking those items.

For the "Toner almost empty" message do an NVRAM clear of the ENGINE.....it also fixes the "Black toner empty" issue in some instances.
