CONFIGURATION SETUP
Are you set up for the right Interface?
Are you set up for the right interface? Did you select the Keyboard Wedge
cable but set the scanner for RS-232 or Wand Emulation? Or did you change
the Keyboard cable to RS-232 but forget to set the scanner interface to RS-232
as well? Set the scanner to its default settings, then select the correct interface
based upon the cable and input you are using.
Symptom ---- The LED lighting is stuck, and no function at all, even
triggered the scanner.
Solution ---- Set the scanner to default condition, and choose the
right interfaces.
Is the proper symbology enabled?
Each bar code symbology can be individually enabled or disabled. It is
suggested that you enable only those that you will be scanning, thereby
eliminating the possibility of mis reads from the scanning of other symbologies.
Does the selected bar code symbology conı guration match the bar
code(s) being read?
Scanned data from each bar code symbology can be restricted to eliminate the
scanning of unused symbologies.
The restrictions are individually set for each symbology
POOR BAR CODE QUALITY
The third problem area has nothing to do with the scanner, but rather the
printed quality of the bar code and/or the scanning technique employed.
TOLERANCE OF BAR CODE
A bar code may have a tolerance. Normally, the tolerances are caused by
bar code font software or a printer. Software with a proven reputation should
be chosen to generate bar codes. If the printed bar codes are distorted, the
scanner might not recognize them.
It is very difficult to get a good read from a poor quality bar code unless it is
scanned many times. As the quality of the symbology drops, the chances for
undetected error increase. A bar code Check Digit Veriıcation (CDV) should be
used to check the quality of the suspect bar codes.
