POSSIBLE
CAUSE(S)
The unit is scanning
a particular
symbology that is not
enabled.
The scanner 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 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 print quality of
the bar code is
suspect.
Check the character
length lock.
The aspect ratio of
the bar code is out of
tolerance.
UPC/EAN is enabled by default.
Verify that the type of bar code being read has been enabled.
Verify that the bar code being scanned falls into the configured
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 host systems
requirements. Make sure that the scanner is connected to the
proper host port.
Check the print mode. The type of printer could be the
problem. Change print settings. For example change the print
mode to
econo or high speed.
