Possible Solutions
Ensure the host has power, and is
on. If the scanner uses a separate
power supply, ensure it's connect-
ed to a working AC outlet.
Check for loose cable connec-
tions.
Ensure scanner is programmed to
read the bar code type you are
scanning.
Try scanning other bar codes of
the same bar code type.
Move the bar code closer to the
scanner's exit window.
Press the trigger to activate de-
coding. Follow directions on page
4.
See the technical person in
charge of scanning.
Scan the appropriate host type
programming bar code.
• Ensure proper host is selected.
• For RS-232, ensure the scan-
ner's communication parame-
ters match the POS host's
settings.
• For keyboard wedge, ensure
scanner is programmed with
the correct country code and
that the CAPS LOCK key is off.
• Ensure editing options (e.g.,
UPCE-to-UPCA Conversion)
are properly programmed.
