I have a stack of documents in the ADF unit, however when I try to scan through the Epson Twain Driver I get a message that THE DOCUMENT FEEDER IS OUT OF PAPER.

• The document(s) may not be fully inserted into the paper pickup area in the unit or the paper sensor is not being triggered. Re-insert the document(s) and/or lift the cover to the ADF and verify that the paper sensor is being triggered, close the cover and try scanning again.
