clean that small glass on printer if problem still continue open all machine and try blow it blower machine!

check for yhe printing settings eg print rough or smooth copies

The line is only in your copies?????
If so you problably have the mirror scanner durty.
Make a print and see if the line are stil there. If so, open the front door and next to the toner unit you will see the fotoconductor unit. inside you have the drum. I advise you to change not only the drum but also the blade.
Just make sure the line apaned also copy and print. If so you are right, the drum is faulty.
Good luke

I would pull the black cartridge out and clean it with a Qtip and a little bit of alcohol. Reinstall the cartridge and try printing again.

You have a bad SCANNER BLOCK..

first, the line are in all printing pages, or only when you make copies?,
if the line are in all printing pages, maybe your fuser has damage the fuser film sleeve,(aprox, 10-20 dlls), if only this line are when you make copies, maybe the glass in the scanner are dirty(clean and try).
i expect this solution your problem

Take a look at your drum. If there's a green tab on the exterior, move that all the way to the left. That should get rid of the black line.

Open up the document feeder and clean the scanner glass

I was getting a verticle black line and I had to clean the glass, the long white bar above the glass, and the white and black rollers before my problem was solved.
