HP Laser Jet 6L Model C3990A Black Page A page is completely black
A page is completely black.
HP Manual Advice 3 below:
1a.The toner cartridge may not be installed properly. Remove the cartridge and reinsert it. Done. No use!
1b·The toner cartridge may be defective. Replace it. Done. No use!
2·There may be discontinuities in the high-voltage contact points. Clean the high voltage contact points on the toner cartridge and transfer roller. (See Figures 7-5 and 7-6.) I don't know where these points are and how to clean them. HP Manual does not carry the requisite figures! Can you help please?
3· Replace the DC Controller or Laser/Scanner unit. What do these cost? More than the present day cost of a basic home-use
monochrome laser printer- about INR. Rs,7,000.-? Please guide me!

I think you've done everything you can yourself. Printers are mysterious electronic devices best left to professionals. However, as you have stated, it might not be worth the cost. That was a very good printer & has lasted a long time, more than 10 years?. You can now get a new HP LaserJet for half the cost of the 6L when it was new. I'm sure the new toner cartridge was expensive.
