Duplex scanning not available

Post by derek_k » Wed May 12, 2010 2:16 am

I can't seem to get duplex scanning working with HP Scanjet 5000 or 7000 devices. The capability is clearly there as I can do a duplex scan from the Windows image acquisition tool, but the VSTwain.Duplex property is always DuplexMode.None (using either the WIA or TWAIN device).

Any ideas?

You should check available duplex modes before using the duplex. Please run our Advanced Demo, select he scanner, press the "Get Source info" button and check which duplex modes are available.

Best regards, Alexander
