Possible Cause(s)
The unit is trying to
scan a particular
symbology that is not
enabled.
The unit has been
programmed for a
character length lock or
a minimum length and
the 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.
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.
Solution
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.
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.
The type of printer and/or the
printer settings could be the
problem.
Check the print mode or
change the printer settings.
For example change to econo
mode or high speed.
