Multifunction EPSON WF2520 - ADF not working under Precise 12.04

[Apanta]

Hi all.
Installed Epson WF2520 under Precise 12.04, using Epson drivers downloaded from Epson website.
Everything works except ADF (Automatic Document Feeder).
The scan always starts as if there was the original sheet on the scanner glass only, while the multi-feed sheets mechanism is not acivated.
How can I fix?
(under Win XP ADF is perfectly running)
Thanks in advance

Ok, solved by myself.
Just setting, on acquire button, the option: "Charge sheets from ADF"
Very simple (After I've discovered)
