Symbol MS2204 and MS2204VHD Scan Patterns
The Symbol MS2204 and MS2204VHD generate different scan patterns (Smart Raster and High Density Single 
Scan Line) based on the software command received at the interface. The raster pattern can be used to read 1D 
bar codes and PDF417 symbols.
Smart Raster Scan Pattern
The Symbol MS2204 and MS2204VHD can create a single line which opens vertically to read PDF417 symbols 
using the Smart Raster feature. This feature autodetects the type of bar code being scanned and adjusts its pattern 
accordingly, providing optimal performance on 1D, PDF417, GS1 DataBar, and Composite codes.

Raster Scan Pattern
High Density Single Scan Line Scan Pattern
The High Density single scan line appears as a "mini" raster and scans multiple areas of 
1D codes to swiftly and accurately capture data on poorly printed and damaged bar codes.

NOTE
The Symbol MS2204 and MS2204VHD also support omnidirectional and semi-omnidirectional scan 
patterns, but are not optimized for these patterns.
Stage 1: “Slab” Raster Pattern
Stage 2: Open Raster Pattern
