♦Scan Type
Selects the feeding device.
The image scanner uses a document bed called the flat bed as well as an automatic document feeder (ADF) for feeding scanned document. The ADF usually enables the documents to be scanned only once. The flat bed allows scanning the same documents repeatedly.
♦Flatbed
Reads a document placed on the flat bed of the device.
♦ADF (Simplex)
Reads the document on the device's automatic document feeder (ADF). Here, only one side is read.
♦ADF (Duplex)
To scan both the front and the back of a page, select this option.
If this option is selected, the document is scanned in the "front to back to front to back ..." order.
This option can be used only for scanner models that support duplex scanning.
The "Duplex Function" requires that the calling application supports "continuous scan." If the application does not support "continuous scan," only the data for the front side of the page is passed to the application.
Some scanner models do not support this option. See "Relevant Image Scanner Specification" in the Appendix.
♦Long page (front)
To scan the entire side of a long page whose length exceeds the vertical size of an A3 sheet, select this option.
The front side and back side can be specified using the same method used for ADF.
If this option is selected, the "Paper Size Setting" dialog box opens. Specify the size of the document to be scanned.
In this mode, however, the preview window cannot be displayed and the scanning area cannot be specified.
Scanner models that do not support this option do not display the "Scan Type" selection item.
