pattern opens to a full, optimized raster pattern as soon as the scanner is properly aligned over
the bar code.
Figure 3-1. LS 6800 Aiming and Scanning Patterns
For best operation in smart raster mode, keep the scan pattern as parallel to the symbol’s rows
as possible, keep the bar code as still as possible, and hold the bar code at an angle which does
not give specular reflection (see Specular Reflection on page 3-8). Also, the bar code should
be in good condition.
Unless otherwise programmed, the LS 6800 operates with Smart Raster performance.
Slab Only Raster
Scanner activation creates a slab raster pattern which does not open vertically, regardless of
bar code type. This may provide optimal performance on small PDF417 and 1D bar codes.
Always Raster
The LS 6800 directly opens to a full raster pattern or to the user-programmed size whenever
the scanner is activated.
Programmable Raster
The user programs the height of the raster pattern and the rate at which it expands. Scanner
activation creates the slab raster pattern which only opens for PDF417 bar codes, useful when
decoding low-profile 1D and 2D bar codes where over-scanning is not desired. Note that the
