Hi all,

I'm new here so some help and advice please
i have a MFC 9330CDW and the prints are coming out with black streaks, sometimes you can't read it at all faded print. but not always!! sometimes the printer is working fine but then sometimes the problems begins. i tried inserted a new black toner works fine at the beginning and then the problem with the streaks and faded print. try contacting brother support with no actual result. try switching the black and cyan works for a few prints only fine. at last i changed the main pcb and high voltage pcb but no.... after a few prints you see streaks and faded print outs again

can anyone tell whats wrong with the printer?????

Have you try replacing the black drum unit? Are you using OEM or Generic toner cartridges?
