Black Streaks on Edges of Paper
My brother printer is leaving black streaks on the edges of the paper. I am using remanufactured toners. I have not had this problem until I bought a new drum and toner. Now all toners are leaving streaks or spots.
Look at the surface of the drum. Can you see the streaks on the edges. There is a blade that is supposed to clean the drum. You can try rotating the drum with your fingers to see if they go away. If they do it is the toner causing it. If they don't, it's the drum unit due to a bad blade.
