Thanks for the tip...the problem is NOT a black line but a wide yellow line on the right side of the paper. It starts out about a quarter of the page in width and diminishes in size to about a half inch in width after many repeated scans.
The glass IS clean , and even when the glass had some smudges here and there, I never had a yellow stripe problem!
Scanner bulb is bright and even the entire length of bulb (no dark areas) so I don't think it is the bulb!

I will try to explain what is happening here. Basically, the PCU's are what puts the toner to the paper. As the parts spin, if there is clumped up toner in there, you will get the "light" streaks on your print out and the streaks will run the entire length of the page for that 1 color (or black). If this is your problem, then here is what I do.
This is messy, get a plastic bag - preferable something you can see through.
Get a feel for where the opening slider is on the top of the PCU and slide it open and hold it open in the bag.
Turn the PCU upside down and shake out all of the loose toner, you will have to turn the unit "to and fro" while shaking and banging it lightly.
Sometimes this will free up the clump of toner that is built up in between the sides of the toner trap and the roller. There's 1 roller that is constantly "dipped" in toner and the other roller that pulls the toner that is needed off of the "dipped" roller to apply to the paper. The one that is "dipped" is having the toner rubbed off by a clump of toner prior to getting to the other roller therefore only transferring a reduced amount of toner where the buildup is.
I have also on the Black PCU have removed the top 2 screws, taken off the green end cap (watch for the 2 plastic plugs that will fall), flicked the spring clips off of both ends and removed the 1 gear to pull out the roller assembly inside the PCU and used a high pressure blower (or canned air) to clean out any clumps. I don't recommend this to anyone that is not mechanically inclined. You can try to blow out the unit through the small slider opening on the top, but you may not get to the part where the streak is.
Good luck. Be sure to rate this post if it helps.

Usually if there are streaks you need to change the pcu that is the same color as the lines. If the streaks are gray it also could be the fuser, but i would think it is the pcu.

If you remove the drum, inside where the drum is a small glass panel if you clean this the white line will go away.

Testimonial: "Yew, this is what I did and it cured the problem. The toners had leaked and made a spot on the laser. Thanks"
