I cannot scan using the Automatic Document Feeder. What should I do?

• Make sure the optional Automatic Document Feeder is installed correctly. See Installing the Automatic Document Feeder for instructions.
  
  Make sure Auto Detect, ADF, or Document Table is selected as the Document Source using either Office Mode or Professional Mode in Epson Scan. See Scanning Using the Automatic Document Feeder for instructions.
  
  If the Automatic Document Feeder is open, close it and try scanning again.
