Loading documents manually
You can load documents manually even when the Automatic
Document Feeder is installed.
Lift the Automatic Document Feeder and place the document on
the document table. Then lower the Automatic Document Feeder
and scan the document.
Note:
Opening the Automatic Document Feeder or its cover while it is
operating results in an option error and paper feeding stops.
Always close the Automatic Document Feeder and its cover before
scanning. If you are scanning thick material or documents of more
than 2 cm in height, the Automatic Document Feeder can be left in
the upright position.
Be sure to select Flatbed in the Document Source settings in
EPSON TWAIN.
When scanning thin documents, you may see an impression of the
underside of the Automatic Document Feeder in your scans. If so,
change to using the document cover instead of the Automatic
Document Feeder.
