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 print quality of the bar
code is suspect.
Check the character length
lock.
The aspect ratio of the bar
code is out of tolerance.
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.
Solution
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 a higher print
quality or DPI resolution.
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.
