I'm aware of that and hadn't planned on taking the machine to bits, just simple things.
We do have a company that can carry out the work, however they were not sure on what the problem was without checking all the possibilities I listed, they charge an extortion rate so I'd like to have a better idea as to what it may be before we call them back.
I would suggest that you draw an arrow on the copy to show the copypaper feeding direction. Or else if it were me, I would explain it this way: The streaks are ALONG FEED or ACROSS FEED direction. If they appear along feed direction and the many suggestions don't seem to work, then you should check the shutter for presence of any unwanted particles/tissues if there is any, also check the dust proofing glass if the is any dirt/toner.
Here's a new picture showing feed direction.

i have encountered this kind of problem i changed the main charge assembly,cause when i try to replaced the corona wires the problem is still there...i think the problem was in the corona grid....
For my money, clean blade replacement, and drum polishing are the most likely candidates according to the sample provided, which shows no edge erasing in the area of the defect. If corona was the issue, you would still have edge erasing going on. If drum clean blade fails, dirty copies edge to edge is the normal symptom...
