MK2000 Introduction
Smart Raster
In Smart Raster mode, a single scan line pattern appears. If the bar code is a standard bar
code, the scanner decodes the symbol. If the bar code is a 2-D bar code, the scanning
patterns open up to a full, optimized Raster pattern as soon as the scanner is properly
aligned over the bar code.
Figure 1-5. Smart Raster Scanning Pattern
When using the Raster pattern, the pattern must cover the top and bottom of the 2D symbol.
If it does not completely cover the bar code pull the bar code further away until the pattern
completely covers the bar code. Make sure the scan pattern extends at least three quarters
of an inch beyond the edges of the bar code.
