Possible Causes
Beeper disabled. No tone
selected
Scanning a particular
symbology that is not
enabled
The scanner has been
programmed for a
character length lock, or a
minimum length and bar
code being scanned does
not satisfy the
programmed 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 beeper. Select tone
UPC/EAN, Code 39, interleaved 2 of
5, Code 93, Code 128 and Codabar
are enabled by default. Verify that
the type of bar code being read has
been selected
Verify that the bar code that is being
scanned falls into the criteria
(Typical of Non-UPC/EAN codes)
The scanner defaults to a minimum
of 3 character bar code
If the scanner is setup to support
ACK/NAK, RTS/CTS, XON/XOFF
or D/E, 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.
Most sure that the scanner is
connected to the proper host port
