Possible Cause(s)
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.
The com port at the
host is not working or is
not configured
properly.
The cable is not
connected to the
proper com port.
The com port is not
operating properly.
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.
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.
Check to make sure that the baud rate and parity of
the scanner and the communication port match and
the program is looking for RS232 data.
