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 or in the decoder to which the imager connects.
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 key or the 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
"Prefix/Suffix Overview" for further information.
Does the imager read the bar code incorrectly?
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 2 and Chapter 3
•
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 Chapter 7.
The imager won’t read your bar code at all.
•
Scan the sample bar codes in the back of this manual. If the imager reads the
sample bar codes, check that your bar code is readable. Verify that your bar code symbology
is enabled (see Chapter 7).
•
If the imager still can’t read the sample bar codes, scan "All Symbologies".
If you aren’t sure what programming options have been set in the imager, or if you want the
factory default settings restored, scan Standard Product Default Settings.
