Duplex WIA scan properties missing

0
votes

I can't access/find the duplex property / setting on my scanner via Powershell and via WIA 2.0 .

I 've installed the correct drivers but it seems, that alot of properties are missing (see below).

Am I reading from the wrong device properties? -> device.Properties["Document Handling Select"] = 5 (found here WIA 2.0 Duplex scanning ).

The scanner scans both pages in 1 turn (double-sided scan).

Tried several "fixes" of other questions, including calling the image item.transfer twice - doesn't provide the backpage though.

What works:

  • Everything, including scanning a page and saving it into a .tiff file

What doesn't work:

  • Duplex - I 've searched millions of sites, WIA 2.0 documentation, but I can't seem to find the right property to set the device.Properties["Document Handling Select"] = 5 (found here WIA 2.0 Duplex scanning )
  • The Scanner is Duplex and works with duplex in every standard scan setting

Powershell snippet

While ($true) {
"in While"
Try{

$deviceManager = new-object -ComObject WIA.DeviceManager
"Devices: " + $deviceManager.DeviceInfos.Count()
$device = $deviceManager.DeviceInfos.Item(1).Connect()

} catch {
    "while break"
    $error
    break 
}

$x = 1
while ($x -lt 17){

$device.Properties($x)
$x = $x + 1
}

$imageProcess = new-object -ComObject WIA.ImageProcess

$wiaFormatTIFF = "{B96B3CB1-0728-11D3-9D7B-0000F81EF32E}"

foreach ($item in $device.Items) {
    "device items: " + $device.Items.Count
    $image = $item.Transfer($wiaFormatTIFF)
    $imageback = $item.Transfer($wiaFormatTIFF)

Okay, actually the scanner didn't have the property for duplex, while beeing duplex. Tried it with another scanner and with that property it works.

Try {   
    "device items: " + $device.Items.Count

    $device.Properties["3088"].Value = 5 <--- Duplex property 5, ID 3088
    $device.Properties["3087"].Value
    $imageback = $item.Transfer($wiaFormatTIFF)

} catch {
    "while break"
    $error
    $killwhile = 1
    break 
}
