All the support and forum research says that replacing the magenta imaging unit should correct this problem (massive streaks in the magenta), but a brand new unit made not a bit of improvement. I can't find any other suggestions or recomendations for a fix. Help!?!
In this it is possible to have a Led Print Head defective, or to be so dirty to take it out to clean it proper. To see if it is dirty pull out all the drums and with a light take a look and compare the four LED. Other wise it is possible to have a problem with Magenta Developer Housing or with the Image Belt Transfer (this is the least likely).
