TROUBLESHOOTING GUIDE
Symptoms Possible Cause(s) Solution
All Interfaces
The unit is trying to
scan a particular
symbology that is not
enabled.
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
The unit powers
up but does not
scan and/or
beep.
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.
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.
The unit scans
a bar code, but
locks up after
the first scan
(the white LED
stays on).
The scanner is
configured to support
some form of host
handshaking but is not
receiving the signal.
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.
The unit scans
but the data
transmitted to
the host is
incorrect.
The scanner’s data
format does not match
the host system
requirements.
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.
There are
multiple scans
upon
presentation of
code.
The same symbol
timeout is set too
short.
Adjust the same symbol timeout
for a longer time increment.
