Black vertical line on scans

[MrsPhilli]

I have an ImageClass mf4370dn and it suddenly has a black vertical line that is printing when I scan a document. It does not show up when I copy it. How do I repair the equipment? Thanks!

I followed your instructions. Still getting line. There is a tiny little black spec on the top white portion that sits on the glass when closed. Could that be it. I tried glass cleaner. It would not come out.

That worked for me! Thanks.

I just started to have this issue.  I have run the "fix/clean" twice and no black ink on the paper.  I cleaned the rollers but still the black solid lines.......  HELP.  Thank you

I can't see your scanner, but scanners have to be perfectly clean or else you will see some line if there's anything resting on the glass where the scanner moves.

Sometimes cleaner will not get everything.  I had to use a plastice credit card and lightly scape the surface to get it completely clean

If the line is occuring when printing to the device, it is most likely the Drum or Imaging unit. You will need to buy a new one to remedy the line.

I have an Canon Imagerunner 3035. It suddenly has been showing thick vertical lines. It also notce that it has a greater tendency to do paper jams and seem to be running hot. 

I disconneted the machine however, I am concerned that reconnecting is not going to be enough. What do you recommend?

mr 19th !

Thank you so much! Due to your precise description, I was able to clean the smudge off the little glass on my MX 922 and eliminate my problem!

I have this same problem but only on the feeder loads, manual placement yields exact copies. Why?
