Smart Raster
In Smart Raster mode, a single scan line pattern appears and decodes a standard bar code. If a 2D bar code is
presented, the scanning pattern opens up to a full, optimized raster pattern.
Figure 1-6
Smart Raster Scanning Pattern
The raster pattern must cover the top and bottom of a 2D symbol. If not, 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.
Figure 1-7
Raster Pattern Expanded Over PDF417 Bar Code
If the vertical scan pattern is not high enough to cover a “tall” PDF417 symbol, move the bar code slowly down
toward the bottom of the scan beam, keeping the beam horizontal to the rows, then slowly back up to the top.
Alternatively, move the bar code further away from the scanner until the scan pattern covers a larger portion of the
bar code in the vertical direction.
Figure 1-8
Moving Scan Pattern Upward and Downward on “Tall” PDF417 Bar Code
The scan beam does not have to be perfectly parallel with the top and bottom of the symbol (up to a 4
o
tilt is
permitted).
