Automatic document feeder won't work after clearing jam. I suspect there's a bit of paper stuck in there somewhere bu can't find it

"Document in ADF", usually means that there is a document in the Automatic Document Feeder. Or to put it differently, there is a paper jam in the document feeder (probably of the scanner part).
The fix is to check the feeder and clear the jam. Sometimes it indicates there is a piece of paper stuck or a faulty paper detector.

my scaner icon window show this messege:
an automatic socument feeder paper jam has been detected. clear the jam and try scaning again
