Symbologies
Postal Symbologies
Note: Postal Symbologies
are only supported when
Q-Mode
is enabled.
Important: Postal Symbologies
must have a pixels-per-element value of no more than
7
to be decoded reliably by the Quadrus MINI Imager.
The imager must be configured to specific read range, field of view, and camera parameters
before decoding Postal Symbologies.
For optimal decode results with a Standard Density (SD) imager:
• Set
Focal Distance
to
6”
and configure gain and shutter settings for a high contrast image.
• Enable
Pixel Sub-Sampling
at
4:1
.
• Position the imager
3.5”
to
7”
from the symbol (5-10” if Pixel Sub-Sampling is disabled).
• Position the symbol as close to the center of the imager’s field of view as possible.
Note:
Measurements based on a 16 mil (60 dpi) POSTNET symbol.
Position the postal symbol in the center
of the imager’s field of view.
