The following image shows a cheque scanned in duplex mode without Merge two sides enabled, and the same
cheque scanned with Merge two sides enabled. When Merge two sides is not enabled, side 1 and side 2 of the
cheque are saved in two separate files (IMG_0001 and IMG_0002 respectively). With Merge two sides enabled,
both sides of the cheque are in a single file (IMG_0003). If you are scanning a stack of items using a multipage
file format, such as a PDF file, then each page in the final file will have both the front and back images of the
scanned items.
Height threshold
Input the maximum height of images to be merged. The sides will not be merged if the height of either the front
or rear image exceeds this value. For example, if you are scanning a batch of mixed documents such as cheques
and statements, you may want both sides of the cheques merged into one image but not the statements. The
Height threshold needs to be lower than the length of the documents you do not want merged into a single file.
Select one of the options in the Merge two sides list to enable this field. Note that you will also need to enable
Long document if you want to have the maximum height threshold be longer than 17.
Advanced Panel Options
The options in this panel may also appear in the Main panel, but with additional settings for you to fine-tune the
feature you've selected. Select the Advanced source configuration mode to show this panel.
Skip Blank Originals
Select this option to have the scanner detect if a blank page has been fed through the scanner, and remove it
from the final file. Typically you might use this option when scanning a stack of two-sided pages which have a
number of blank sides.
