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.

Check overlapping

The overlapping of the transmitted document is checked by the sensor in the device. A double feed is detected by overlapping when more than one document is sent.

Check overlapping and length

The overlapping and length of the transmitted document are checked.

For example, the detection accuracy can be improved by using [Check thickness] or [Check overlapping] for continuous scanning of forms that have different lengths and [Check length] for scanning of forms that have different thicknesses.

Depending on scanner model, the selectable items are different. Refer to “Relevant Image Scanner Specification” of Appendix.

♦Pre-Pick

It specifies whether a document is picked and carried in front of the scanning position before starting scanning operation at the ADF scanning.

Disable

Pre-Pick is not performed.

A document is picked and carried in front of the scanning position, after starting scanning operation.

Enable

Pre-Pick is performed.

A document is picked and carried in front of the scanning position, before starting scanning operation.

Panel setting

The setting of device is followed.

*When selecting “Enable,” you can scan faster than when selecting “Disable,” because of Pre-Pick process.

When selecting “Enable,” if you cancel during the ADF scanning, a document remains in the scanner in the Pre-Pick status.
