Hi,
For laser problem, the image will be feint.
In this case, I suppose that you should try to adjust HV of developing, primary charging or replace HV board

Are all machine carters mounted ? An external light may cause this print quality.

Fuser???? Crash it after transfer and see what you have. I have seen fuser star wheel get caked with toner and drag unfused image. Is it a sharp line? Is it perfectly straight? Need more info. And fluff in the laser light path will give you a light line,not dark( unless its ir 5000,6570,etc...where laser discharges white area).
