Multicode Data Formatting may yield multiple unexpected and undesired outputs when a label (most likely on a complex label) passes through the scanner's field of view. This problem happens when the complex label’s barcodes can be matched by more than one group (for example, Group 1 represents all barcodes present, and Group 2 represent some barcodes present).
As the label is moving through the field of view, it is first partially read (some of the barcodes in the field of view in Frame 2).
Then, the second decode occurs as it is fully read (all the barcodes in the field of view in Frame 3).
This yields two different outputs (instead of the expected single output) from the presentation of a label. This problem is driven by a complex label inadvertently matching two different MDF rules/groups, thereby yielding two outputs.
