Brother printer - no, I don't need to replace the toner!!!!
I'm writing re: our printer at work, so hope I can get an answer soon!
This thing has been nagging us about replacing toner for weeks now. IT LOOKS FINE. Print is still solid and black, and there is not the least bit of gray.
Now it is just flat out refusing to work unless I replace the toner cartridge and it keeps plastering my computer screen with nagging about cleaning the corona wire.
I've done the usual shaking of the toner cartridge and putting it back in, but it is not being fooled.
Is this in fact what's going on, why it isn't working - and if so, is there some way I can override it? How does it know I am not obeying it and inserting a new cartridge?
Or - looking at it another way, how do I know it is telling the truth?
This machine is getting on my last nerve!
