I try to set FeederEnabled property, but I get exception - "Error to set capability value."
My scaner model is hp scanjet 5550c.
Pls, see code below
Code: Select all
if (vsTwain.FeederPresent)
{
vsTwain.Capability = (int)DeviceCapability.FeederEnabled;
if (vsTwain.IsCapSupported())
{
//vsTwain.AutoFeed = false;
vsTwain.FeederEnabled = _scanSettings.IsDocumentFeederEnabled; // Here "Error to set capability value."-exception is thrown !!!!!!!!!!!!!!!!!!!!!!!
}
}
