26
Possible Causes
Scanning a particular
symbology that is not
enabled
The scanner has
been programmed for
a character length
lock, or a minimum
length and 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
The aspect ratio of
the bar code is out of
tolerance
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 3 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. Most sure that the
scanner is connected to the
proper host port.
Check print mode. The type of
printer could be the problem.
Change print settings. i.e. change
to econo mode or high speed.
