WIA Setting up page size does not work

Im trying to make an app that can scan documents using C# and WIA. But I have come across a problem when setting up the page size property. When I run the scanning process my app throws an error:

An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in DigiKnjiga.exe

Additional information: Exception from HRESULT: 0x80210067

I have tried this using these properties: PageSize(3097), PageWidth(3098) & PageHeight(3099), HorizontalExtent(6151) & VerticalExtent(6152). But setting any of these values throws the before mentioned exception.

Here is the event that starts the scanning process:

private void scanNew_Click(object sender, EventArgs e)
    {
        if (Scanner.ChosenDevice > 0)
        {
            Device = deviceManager.DeviceInfos[Scanner.ChosenDevice].Connect();

            switch (Scanner.ColorCode)
            {
                case 0://color
                    Device.Items[1].Properties["6146"].set_Value(1);
                    break;
                case 1://grayscale
                    Device.Items[1].Properties["6146"].set_Value(2);
                    break;
                case 2://black and white
                    Device.Items[1].Properties["6146"].set_Value(4);
                    break;
            }

            //(DPI)
            Device.Items[1].Properties["6147"].set_Value(Scanner.DPI);
            Device.Items[1].Properties["6148"].set_Value(Scanner.DPI);

            //brightness
            Device.Items[1].Properties["Brightness"].set_Value(Scanner.Brightness);

            //contrast
            Device.Items[1].Properties["Contrast"].set_Value(Scanner.Contrast);

            switch (Scanner.Format)
            {
