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 am having the same issue with scanning or copying on the ADF.  A black line appears on every scan through the ADF only.  I've tried all the hints on cleaning and am disappointed as my printer is barely a year old.  My printer is a Maxify MB5420.  What else is there to try to fix?

Thank you.-

Hi J, check out my post number 36. The line causing the problem is extremly hard to see.but it is there. The credit card trick works well and then another good cleaning. Good luck. MP

That only seems to work if the line appears when scanning using the ADF. Thas it not my issue. It only appears for my when scanning on the platen. Scanning letter size paper with the ADF is fine.

Thank you!  It wasn't easy, but your solution resolved my problem, too, and saved me from buying a new printer/copier.

Worked. But streak was not caused by main glass. I cleaned it twice. It was on the little thin strip of glass with the scanner camera. Working perfect again. Maybe it was caused by putting through a freshly printed page to make extra copies, ink wasn't quite dry enough. Any event thanks for the tip.
