Black Line down the page

[ Edited ]

I keeping getting a black line down the page no matter what I do. I have cleaned the glass, changed the ink cartridge, ran the cleaning program through the menu screen. The line shows up not matter what I do. HELP!


I have a canon imageclass MF4890dw


Update - the blackline runs vertical down the left side of the page only.  It happens when I print from the computer to the printer, when I scan copies on the glass and through the top loader, and when I fax. Again I have cleaning the glass, removed the plastic strip and clean that and I have run the cleaning program through the menu screen.

Hi, adraper1127!

So that the Community can help you better, please let us know if this black line is showing up only on printouts, in images produced by the scanner mechanism, or both. That, and any other details you'd like to give will help the Community better understand your issue!

If this is a time-sensitive matter, search our knowledge base or contact our US-based technical support team at

Thanks and have a great day!
