If this problem is on a laser printer there is only one thing causing the issue.

More than likely there is a permanent scratch in the surface of the image drum that goes all the way around the cylinder.

To verify this simply remove the toner cartridge from the unit and turn it over. You should see a small plastic shutter mechanism which is covering the photosensitive drum. Carefully open the cover without touching the drum surface with your fingers as the oils on your skin will damage the drum surface further. If you see a mark in the drum surface, that is your problem and the toner/drum unit will need to be replaced. This most likely was caused by something that was accidentally introduced into the imaging area of the unit. Before putting a new toner/drum cartridge into your printer verify that there are no obstructions like a paperclip or even smaller a staple as this will get caught in the new unit and cause the same problem. This problem is not covered by manufacture warranty and therefore you will need to bit the bullet and buy a new one.

Hope this helps solve your problem. I used to work as a Systems Engineer for Kyocera-Mita a printer and copier manufacturer so I have seen this issue hundreds of times over the past 20 years.

Cheers,

Keith

My printer has started printing a black line down the edge of the paper?


Remove the laser print cartridge, shake it lightly, and place it back into your printer. That should solve the problem.

Black line on copy and fax functions


Clean the paper path for the scan/fax portion. The original goes in and as the document is "read" a spot of dirt is causing the black line down the page because it is picked up in the copy area.

When you print each page has a gray/black line running down the page from top to bottom about 2.5 inches from the edge of the paper. Sometimes it is darker and other times it is lighter. We have tried...


While the line is showing up on the output pages.
Stop printing and put paper in the manual feed tray (tray 1).
Start printing again. As a page gets pulled into the printer about 1/2 way open the top cover.
Pull out the toner and look at the page inside the printer. If it doesn't have the grey/black line, get the fuser replaced. It is defective.

I always have a black line down the middle of the page when i scan. help


If there's a black line when scanning but not when printing, you need to clean the scan bed. Either the glass has something on it or check the paper path if you're using the ADF. A single ink spot either place will print a line down the whole length of your scan.

I have a grey/black line all the way down the right hand side of the page


Run a half test.
Put paper in the manual feed tray.
Print something, anything
When the paper is 1/2 way into the printer, open the cover.
Pull out the toner cartridge. Look down at the paper.
Does it have a black line on the right side?
If yes, replace the cartridge. If no, replace the fuser.

Thick black line on printed page


If the line runs the way that the paper does I.E. vertical on a portrait then it is dirty rollers normally.
If you open the lid and wipe the rollers this shoukd reduce or eliminate the black lines.

Black line on back of page


It sounds like you have a black ink leak and it is smearing onto the paper when you print. I don't know any reasons for this except if you topped the black ink up yourself, and didn't re-block the hole you made. Then I guess the ink would gravity drip onto the paper tray while you weren't printing. Otherwise I would suggest changing the print head, but this might be expensive.
