Try cleaning the charger wire on top of the toner/drum unit. It should have a green plastic knob/handle to slide the cleaner left to right and back. Do this several times.

Testimonial: "Thank you many times over for your help. Before seeking your advice I wasted about 25 sheets and time trying to remove excess toner marks 10/10"
SOURCE: black streaks
This is caused by a rotating part that is contaminated, most likely the drum that transfers the toner to paper.
A new drum or drum cartridge is probably needed.
There is a very remote chance that the high voltage that charges the drum is being modulated but I have seen this once in decades of service.
