Brother MFC-7840W with Sheet Feeder - Vertical Line Appears When Scanning But not When Copying

Recently a vertical line has started appearing when I scan documents on my Brother MFC-7840W printer using the sheet feeder. Interestingly the line does not appear when I - copy documents using the sheet feeder - scan from the flatbed - send a document to print. The problem is limited to scanning with the sheet feeder. Any suggestions you might have would be greatly appreciated. Thanks Trip
