You have contamination on the scanner glass you need to clean. This unit has 2 scan heads so you need to make sure both are clean. If the line is on the side that is face up in the document feeder, then lift the lid and clean the slit of glass on the left side. If the line is on the other side then you need to clean the backside scanner. Check YouTube for instructions to do that.

Thanks for your reply.  If you are correct, I see a small black fleck under the glass on the left side pane.  How do I get under the glass to remove or even blow out with compressed air?

Thanks for your quick initial reply
