Scanner Model Panel Options

The options in this panel are specific to the scanner you are using. If you select an option in this panel that also appears on the Main panel, when you return to the Main panel, that option will be selected. Select the Advanced source configuration mode to show this panel.

Detect Double Feeds

Detect double feeds is the scanner's ability to detect when two or more pages are fed through the scanner at the same time. When this option is turned on, ultrasonic waves are aimed at the document to detect multiple pages by the level at which the waves pass through the pages. The accuracy of this sensor depends on paper thickness and whether or not creasing is in the original document.

This option is available in the interface only if the current scanner supports this feature.

Adjusting the sensitivity level

Click on the scanner model panel to set the sensitivity level at which the scanner detects double feeds. Move the slider left or right to adjust the sensitivity level.

•Low works best with paper weight higher than 22lb (80 g/m2 or higher).

•Normal works best with standard printer paper weight 18lb or 20lb (67 - 75 g/m2).

•High works best with paper weight lower than or equal to 16lb (60 g/m2 or lower).

Technical Note:

If you are getting false double feed errors, try cleaning the inside of the scanner. Excessive dust on the sensor can cause false double feed errors. Refer to the maintenance section of the scanner's user guide for instructions on cleaning the scanner.
