G
UIDE
POSSIBLE CAUSE(S)
Scanning a particular
symbology that is not
enabled.
The scanner has been
configured for a
character length lock,
or a minimum length
and bar code being
scanned does not
satisfy 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
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 4 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 the format
required by the host. Make sure
that the scanner is connected to
the proper host port.
