Sounds like you have a scratched lens. If you have another unit, try replacing the lens from that one. If you do not, you will need to replace the complete unit or see if you can find one on Ebay.

How do I get in there safely to clean the mirror?? what do i unscrew first etc.. it still working just fine but the color is going after 15 years and i need to clean the inside.


Hello.
I would not recommend you to touch the mirror. It is hanged sort of reflection surface facing down so it is not real dust collector. You can clean lenses of your CRT tubes (red, green and blue) to improve your picture. Just remove rear cover taking out black and golden screws and you will see dusty lenses right away in the middle of the TV. Use DRY "Bounty" paper towels to remove dust from lenses, don't wet it with any solutions or it will leave film on optics. Just in circular motion move dust to the black plastic edges of lenses. Don't worry about some specs of dust that inevitable will be left behind - they will not affect image at all like thick layer of dust do.
Regards.
Russ.

Wide black lines down the paper. I have changed


Have you changed the Drum unit. Also there is a cleaning pad that you slide across the corona for cleaning. If you leave it in the middle it will give a black line, should be moved all the way to one side.

Have black smudge line in middle of paper have new toner and drum


Try taking out your toners, and on the drum you will see a green button which you can slide from side to side (it's on each of the colored slots). Make sure you put the the white plastic cover up and then it will slide. I hope this will help you.

Black Line down middle


The line is from ink coming up from the absorber pads on the bottom. It needs a good cleaning and a mylar sheet to keep the ink from coming up onto the rollers. A shop repair.

Black line down middle of page


Clean off the glass place where the paper passes when you fax. You'll probably find some foreign matter on it. Wipe it off and you should be good to go.
