Scan Patterns

The scanner emits several scanning patterns, described as follows. To select a pattern, see
4-6.

Single-Line Only

The laser has no up and down scan line movement (no raster).

Multi-Line Smart Raster

The scan line begins as a single line and moves up and down (rasters) when a partial scan of a bar code is
detected, or no bar code is decoded 500 ms after the trigger is pulled. If the scanner detects a PDF417
(Symbol LS4208-PR only), GS1 DataBar, or Composite Code, it immediately rasters, opening to a full, optimized
raster pattern as soon as the scanner is properly aligned over the bar code.

Multi-line Always Raster

Rastering (up and down scan line movement) begins immediately to decode 1D, PDF417 (Symbol LS4208-PR
only), GS1 DataBar, and Composite Codes.
