Detecting a document double feed
This scanner includes a function to detect document double feeds. By 
using this function, the scanner will automatically stop when it detects 
that multiple documents have been fed at the same time. You can also 
specify whether to save the scanned image after scanning has 
finished and continue scanning the document (double feed detection 
ignore function).
To use the double feed detection function, you must first open the 
scanner driver settings screen and enable double feed detection. It is 
also necessary to set [Rapid recovery system] to use the double feed 
detection ignore function.
