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.
Good luck.

Ah, the beauty of digital manipulation :)

In the old days you would have to change the paper in the tray too...

I've been looking online for the glass, and can't locate it. They will charge you a bundle for a piece of glass anyway (I know Konica charges about $50 one).

As to the question of a sensor. If there's no wire on it, there's no sensor. Some manufacturers use a "coating" that goes to a ground wire for anti-static, etc. Most likely, yours doesn't require this.

Also, to prolong the life of the new glass (now don't tell ALL of my secrets) use armor-all, car wax, even pledge (the wood stuff) on a rag and buff the glass. Just a dab will do.

I'll keep looking online for the part for ya.

Good luck!

Most likely your drum unit is worn out. If it reaches the yield of 50k or more, it starts to develop grooves in the drum and toner gets stuck in the groove and is applied to your pages. If you have a service company, they can change it for you. We sell the drum for $220.

Did you try to make sure the primary charge corona unit is it all the way and locked down. Take it out and look to see if the wires are not broken. If the copier has 30k on it, I need to know if the OPC drum has ever been replaced? They are rated for only 10 to 15k print outs. If you really want to know for each page that comes out it has to make 4 copies on the same drum for one out put page. You are not getting a error code? Most of the time if the drum was old or bad you would get a E061. How about the dose the scannig lamp come on? You got me thinking now.... It has been years scine I worked on one.... I'm don't done yet..

Whats the make and model of the copier?
One culprit might be the drum.  If you can take a look at the drum from your copier and you see black lines on it.  It could be scratches on the drum or it may need a new cleaning blade to clean the toner off the drum.
