TASKalfa 3010I intermittent black prints

[Tonerkiller]

We have a 3010i that since it was new very intermittently we will get black prints, then it will work fine. Replaced the drum unit so far and have checked the spring that provides the charge. Next we are ordering a hv. Has anyone else had this issue?

Does this happen with prints and copies?? If only with copies check the Exposure Lamp.
I with both….It is difficult to say…it could be Laser, Exposure Lamp, Main Charge or even the HV PCB.
Good luck

See the question right above your post? "Does it happen on prints and copies or copies only?"

It most certainly is a High voltage arcing problem.
What happened before the lines started. Did you or someone else replace anything or work with the harnesses, maybe pinch a wire? I would clean and trace harnesses/ground/live contacts then test MC, DK, HV in that order.

It happened to me too on a 3011i, I solved it by replacing the drum unit.
