-
You are using Windows Fax and Scan on a Windows 7-based computer.
-
You begin a new scan and then select Feeder(Scan both sides) for duplex-mode scanning.
-
You select Preview to preview the scan.
In this scenario, the preview scanning may fail, and you receive the following error message:
An error occurred while setting scanner properties. If another program is scanning, please wait for it to complete and try again.
Cause

Resolution
You may be unable to preview when you are scanning both sides by using a duplex-capable ADF Web Services scanner. To preview a scan, manually select single-side (simplex) scanning.Â
