TWAIN Scanning Guide Document Settings
28 User’s Guide
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 (depending on the scanner model).
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.
