2-4 DuraLine™ 2D Imagers
Is the Imager having trouble reading your
symbols?
If the Imager isn’t reading symbols well, check that the symbols:
• Aren’t smeared, rough, scratched, or exhibiting voids.
• Aren’t coated with frost or water droplets on the surface.
• Are enabled in the Imager (see the Product Reference Guide for
more about symbologies).
Is the bar code displayed but not entered?
The bar code is displayed on the host device correctly, but you still have
to press a key to enter it (the Enter/Return or Tab key, for example).
You need to program a suffix. Programming a suffix enables the Imager
to output the bar code data plus the key you need (such as “CR”) to
enter the data into your application. Refer to the Product Reference
Guide for further information.
Does the Imager read the bar code incor-
rectly?
If the Imager reads a bar code, but the data is not displayed correctly on
the host screen:
• The Imager may not be programmed for the appropriate terminal
interface.
For example, you scan “12345” and the host displays “@es%.”
Reprogram the Imager with the correct Plug and Play or Terminal
selection bar code. See
Chapter 1
and/or the Product Reference
Guide.
• The Imager may not be programmed to output your bar code data
properly.
For example, you scan “12345” and the host displays “A12345B.”
Reprogram the Imager with the proper symbology selections. See
the Product Reference Guide.
