2. The host system power is on (if external power isn’t used).
3. The trigger works.
Is the scanner having trouble reading your symbols?
If the scanner isn’t reading symbols well, check that the symbols:
1. Aren’t smeared, rough, scratched, or exhibiting voids.
2. Aren’t coated with frost or water droplets on the surface.
3. Are enabled in the scanner or in the decoder to which the scanner 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 scanner 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" on page 4-1 for further
information.
Does the scanner read the bar code incorrectly?
If the scanner reads a bar code, but the data is not displayed correctly on the host
screen:
1. The scanner may not be programmed for the appropriate terminal interface.
For example, you scan “12345” and the host displays “@es%.”
Reprogram the scanner with the correct Plug and Play or Terminal selection
bar code. See
Chapter 1
and
Chapter 2
.
2. The scanner may not be programmed to output your bar code data properly.
For example, you scan “12345” and the host displays “A12345B.”
Reprogram the scanner with the proper symbology selections. See
Chapter
7
.
The scanner won’t read your bar code at all.
1. Scan the sample bar codes in the back of this manual. If the scanner reads
the sample bar codes, check that your bar code is readable.
Verify that your bar code symbology is enabled (see
Chapter 7
).
2. If the scanner still can’t read the sample bar codes, scan "All
Symbologies" on page 7-1.
If you aren’t sure what programming options have been set in the scanner, or if
you want the factory default settings restored, scan "Factory Default Settings" on
page 12-4.
