More difficult is the thing designed with the 'Scan to PDF' button on the device, here I was initially repeated an error in I was told that I did not have the keys and their functions.
Only after several attempts via email and a recall of Epson support with me, which would be this error could be remedied with me 'Step by step'. These must be selected under the scanner option, and then click the Register button to select the card and these are then linked with the FunctionB in Windows.
Ultimately, everything works as it is supposed to and I'm very happy with my new Scnanner and the results that it delivers.
Through this procedure, unfortunately only 4 stars for an otherwise excellent device.
