Two Sides

[vmfvmf]

Well, for scanning a single side of the page is working perfect.

I tested on a Lexmark MX711 and Fujitsu fi-6140

But when is for scanning the two sides of the page (i think it would be the duplex option = true) it scan like default option.

Any hint what it could be or maybe how we fix it?

I made some testes and saw that the Scan UI used by TwainDotNet is the same used by LibreOffice, and LibreOffice cant scan two sides too, so it must be something with the Twain package instead of TwainDotNet.

But the Windows Scan and Fax can do with the both sides, but, in its option origin has two option

1. Feed ( one side)
2. Feed (Two sides)

On MFPs to scan two sides usually is used another origin... I'm searching yet, any help will welcome ^^
