Symbol MC3000 - Laser Decode Ranges

MC3000 Integrator GuideA-6
Laser Decode Ranges
The decode ranges provide the decode ranges for barcodes of specified densities. Figure A-3 shows the laser decode ranges and Table
A-4 on page -7 lists the scan ranges for the selected bar code densities. The minimum element width (or “symbol density”) is the
width in mils of the narrowest element (bar or space) in the symbol. The maximum usable length of a symbol at any given range is
shown below.
