The 'Duplex.isSupport()' function doesn't define a duplex scanner #110

Hi, I am using the 'es-400' scanner to test duplex functionality. The 'isSupport' function '_twain32.Capabilities.Duplex.IsSupported(TwQC.GetCurrent)' doesn't define it like a duplex scanner. I tried to set property without check _twain32.Capabilities.DuplexEnabled.Set(true) and it throws an exception 'Saraff.Twain.TwainException: 'Unknown capability.'' In default 'Windows Fax and Scan' app. I can set 'Feeder(scan both sider)'. How can I scan both sides with 'saraff.twain' package? Could you please help me?
