Hi.
I want to change toner hoppers, and in the service manual is written to unlock toner bottles (In service mode) first.
I searched the chapter service mode of the manual for half an hour and couldn't find anything to unlock toner bottles.
Besides, when i open the toner bottle front cover, the dispay says: "Toner bottle cover open" but doesn't switch to the screen where i can select which bottle(s) i want to change...
Can anybody help?
Thanks in advance.
