Possible Causes
The beeper is
disabled and no tone
is selected.
The bar code
symbology trying to
be scanned is not
enabled.
The scanner is trying
to scan a bar code that
does not match the
configured criteria.
The scanner is
configured to support
some form of host
handshaking but is not
receiving the signal.
The scanner's data
format does not
match the host
system requirements.
Solution
Enable the beeper and select a
tone.
UPC/EAN, Code 39, interleaved 2
of 5, Code 93, Code 128, Codabar
and PDF are enabled by default.
Verify that the type of bar code
being read has been selected.
Verify that the bar code being
scanned falls into the configured
criteria (i.e. character length lock or
minimum bar code length settings).
If the scanner is setup to support
ACK/NAK, RTS/CTS, or
XON/XOFF, verify that the host
cable and host are supporting the
handshaking properly.
Verify that the scanner's data
format matches that required by
the host. Make sure that the
scanner is connected to the
proper host port.
