selected (Double Letter) paper size range is used for scanning, the output will adjust to the page size detected.

(However, in case of fi-4860C/fi-4990C/fi-5650C/fi-5750C, this function is not dependent on the setting of [Paper size] because these scanners always scan documents as the maximum paper size and detect the paper size from the scanned data.)

This function does not work properly for some applications.

However, some detection cannot be corrected for example, an unfixed long image, folded corner, document has uneven width for the length of the page.

This function becomes effective only when scanning with the ADF.

(It may detect incorrectly when this function is chosen with flat bed scanning.)

In case of fi-5750C, this function can work correctly with flat bed scanning when “Document holding pad (black)” option (sold separately) is attached on the scanner.

Black Background

If it is selected, the outside of document paper becomes black by using black background during scanning.

White Background

Use it to activate "Overscan". Both [White Background] and "Overscan" need to be selected for making Overscan effective.

If "Overscan" is not selected, [White Background] functions the same as [Disable].

This option may not be supported for some scanners. See "Relevant Image Scanner Specification" in the Appendix.

♦Priority

Setup for speed versus automatic document size detection. Select a small value when scanning speed is the higher priority.

Select a large value when document detection accuracy is the higher priority.

Priority can only be setup when [Automatic Page Size Detection] is selected at [Automatic Size and Skew Detection].

If the selection of [Automatic Page Size Detection] do not makes this function selectable, you do not need to setup this function.

♦Overscan

This function makes the scanned images larger than the original documents by adding margins. This option is available only when [Black Background] or [White Background] is selected for [Automatic Size and Skew detection].
