Abstract
The disclosure includes a fixed retail scanner including a data reader. The data reader includes illumination assemblies that include different LED sub-groups that are co-located within its respective assembly. These illumination assemblies may be identically constructed and installed at various positions within the data reader to provide active illumination for the camera modules. Illumination assemblies are activated together, but only with the first sub-groups from each of the illumination assemblies being activated together at a first time, and only with the second sub-groups from each of the illumination assemblies being activated together at a second time.
