"Double-feed" is a feeding error that occurs when two or more
sheets in the ADF paper chute are fed simultaneously into the

You can set the scanner to detect double-feed, stop scanner
operation, and display an error message.

To set the scanner to detect double-feed, change the settings in the
[TWAIN Driver] dialog box.

The following shows the procedure for changing the settings in this
dialog box.
