// create information about capabilities, which should be set
var twainCapabilitiesInfo = [
{ "capabilityId": "IPixelType", "capabilityValue": 1 },
{ "capabilityId": "IXResolution", "capabilityValue": 200 },

{ "capabilityId": "FeederEnabled", "capabilityValue": true },
{ "capabilityId": "DuplexEnabled", "capabilityValue": true }
];
// set capabilities of TWAIN scanner
var setCapResults = twainDevice.setCapabilities(twainCapabilitiesInfo);
