VueScan works with the Microtek ScanMaker 4850 on Windows.

You need to install a Microtek WIA scanner driver to use this scanner on Windows.

Note that the transparency adapter won't work on Windows because VueScan uses the WIA interface with this scanner and WIA doesn't support transparency adapters.

If you have an iPad, iPhone, Android phone/tablet or Kindle Fire, you can use VueScan Mobile with WiFi scanners or the built-in camera to scan documents.
