I'm not sure if we have a language barrier or not. I ask " are you getting toner into the developer unit? " you answer " I did that " . Are you saying yes? You say " each engine works ". What are you calling an engine?
What are your readings for vsg and vsp? Did they change when you initialized the new developer?
What is the meter count for the developer unit? I have had to change them at around 3 million for internal failures. I haven't seen you say that you've tried another developer unit.
I'm not trying to frustrate you, but I'm not there and don't know what you know, and don't know your level of expertise on the equipment. All I can do is ask questions and try to help you by understanding what you have seen and done. I apologize if this isn't helping at all.
