M283cdw Verticle black line when copying

[dkwdkw]

I'm getting a black line down the middle of the page.  I swapped out the black toner but that did not resolve.  I ran a cleaning cycle but that did not resolve.  Very distinct thin black line from printable edge of top to bottom.  Seems like it happens when doing either black or color copies.  Glass is clean.

Copy from a glass or document feeder leave a black line? What about print? How's that printed?

If only from the feeder, it's dirty glass, the smaller glass one on the left side when you lift the cover.

That was it.  I didn't think about the document feeder using a different sensor that the flatbed.  Cleaning that fixed the problem.  THANKS!!!!!
