Images appearing with black line on them on my Canon 6d

[katrina428]

Hey everyone! So my wonderful Canon 6d is having issues. Everytime I take a picture a black bar appears sideways on it. Can anyone tell me what this is and how to fix it? I tried doing the sensor cleaning that you can select in the camera, but nothing!

I appreciate any help you may have. Thanks!

Did you have it repaired? Having the same issue and wonder if it's worth fixing an old Rebel Xti.
Thanks!
