Bright yellow vertical line on scans

Hello,

We have a less than 6 months old Xerox 6605. Pages fed through the feeder for copying or scanning show a bright yellow line on the right side of the page. 

The flatbed does not show this behavior. I'm not in the same physical location as this copier, I had a user onsite clean the feeder glass. But still seeing that yellow line. It is very bright, not just like a streak.

Any thing else we can look at?

Thanks.
