Raster width specification
In raster scan mode, the BL-700 scans multiple positions of the bar code by swing-
ing the laser beams up and down. Thus, the bar code can be read even if it has a
stain or missing part.
For the up-down width of raster scan (raster width), see the table below:
Model Reading distance Raster width
BL-701 200 mm 10±1 mm
BL-741 300 mm 20±2 mm
BL-781 450 mm 30±3 mm
