Suggestions to minimize the undesired multiple outputs when scanning with MDF.

Scanning Label in a Vertical Orientation
When creating the MDF programming with multiple groups, the Group 1's pattern match should be the most complicated (hardest to match), which equals to the most number of barcodes and criteria. Then Group 2, 3, and so on should be progressively matched more easily.
When defining criteria, avoid enabling an output when the pattern is not matched. Set
Output if NO pattern match
set as
Discard bar code.
Figure Match Setting for Output
Select Discard barcode(s) NOT within the pattern match in the 123Scan MDF setting. For more details, select

Other reasons a label/barcode may not be decoded while in the field of view are as follows:
The label out of focus (too close or too far away).
