Double Feed Detection

This option detects a double feed (occurs when two or more documents are sent) based on

the set condition.

If a double feed is detected when this setting has been turned on, the device will stop and an

error message output.

None

Double feed detection is not performed.

Hardware Setting

A double feed is detected based on the device setting.

Check thickness

The thickness of the transmitted document is checked by the sensor in the device. A

double feed is detected by detecting changes in the thickness when more than one

document is sent.

Check length

The length of the transmitted document is checked by the sensor in the device. A double

feed is detected by detecting changes in the length when more than one document is sent.

Check thickness and length

The thickness and length of the transmitted document are checked.

The detection accuracy can be improved by using [Check thickness] for continuous scanning

of forms that have different lengths and [Check length] for scanning of forms that have

different thicknesses.

Blank page skip

This option skips blank pages (blank pages or completely black pages) during ADF

continuous scanning.

For blank pages, use the [White Dots Ratio] slider to set the skip condition. For black pages,

use the [Black Dots Ratio] slider to set the skip condition.

The value displayed to the right of the slider displays the garbage ratio(*1). If a scanned

document is below this value, it is recognized as a blank page. The setting range is OFF(- -)

and 0.2% to 3.0% (in increments of 0.2%).

−

If a blank page is scanned, increase the value set.

−

If scanning is skipped up to the required document, decrease the value set.
