Either the Fuser/Heating unit is bad, or the optics are dirty.
What you can try to do to narrow it down, is to make a copy but.. STOP the machine in mid process by turning the power off. This will create a paper jam in the machine. If timed properly, your copy should be 1/2 way through the machine with some image on it. (Make sure that you are trying to copy something on the glass). The copy is not FUSED, so the toner will wipe off so be careful not to rub the page against your clothes/sleeve. IF the black line is on the page at this point, the problem is not in the fuser but probably in the fiber optics. If the problem is in the optics and will need to be cleaned. If the black line is NOT on the page at this point, then the fuser unit is bad and needs to be replaced.
Let me know how the copy comes out when you stop the machine in midway and I can see if i can give you any more suggestions.

You could have a broken exposure lamp. Does the scan bar light up when you make a copy? If not that is the problem. You might also ck the contacts on the machine where they touch the toner cartridge. The toner cartridge opens a shutter to the drum when you slid it into the machine and that may be broken.

The waste toner is in the drum unit it's self. If it full you may as well replace the drum unit all togather. Once it is full the drum is just about shoot. If the regestration is off, you may have a problem withe reg. feed clutch. Dose it show up with the paper tray and the manual feed try?
