Possible Cause(s)
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.
The unit is trying to scan
a particular symbology
that is not enabled.
The unit has been
configured for a
character length lock or a
minimum length and the
bar code being scanned
does not satisfy the
configured criteria.
The bar code may have
been printed incorrectly.
The scanner is not
configured correctly for
this type of bar code.
The minimum symbol
length setting does not
work with the 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. Make sure that the scanner is
connected to the proper host port.
UPC/EAN and Code 128 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.
Check if it is a check digit, character or border
problem.
Check if check digits are set properly.
Check if the correct minimum symbol length is set.
