Smart Raster; Scanning 1D (And Rss) Or 2D Bar Codes - Symbol Cyclone M2000 Series Product Reference Manual

Smart Raster

In Smart Raster operation, a trigger pull causes a single scan line pattern to appear. If the
target is a 1-D bar code, the scanner decodes the symbol. If the target 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.

Scanning 1D (and RSS) or 2D Bar Codes

When scanning a bar code:
• Keep the scan pattern parallel to the symbol's rows.
• Hold the scanner as still as possible.
• Hold the scanner at an angle which does not cause specular reflection (see
Specular Reflection
• Hold the scanner close for small symbols, and farther away for large symbols.
Practice shows what works.
