IMAGETEAM™ 2020/4620 System Manual 4 - 13
Decode Search Mode
There are three selectable decode (scanning) modes:
Full Omnidirectional
- Searches for bar code features beginning at the center
of an image, and searches to the image’s limits. This mode reads all
symbologies (including OCR), in any orientation. The Full Omnidirectional
search is very thorough which may slow performance time.
Note: This search mode is the default setting for the IT4620 imager.
Quick Omnidirectional
- This is an abbreviated search for bar code features
around the center region of an image. This mode quickly reads all symbologies
in any orientation. The Quick Omnidirectional mode may miss some off-center
symbols, as well as larger Data Matrix and QR Code symbols.
Advanced Linear Decoding
- Performs quick horizontal linear scans in a center
band of the image. This mode is
not
omnidirectional, but does quickly read linear
and stacked bar codes. Advanced Linear Decoding cannot read 2D, OCR, or
Postal symbols.
Note: This search mode is the default setting for the IT4620 point-and-shoot
PDF imager.
