Symptom
All Interfaces
Scanner beeps at some
bar codes and NOT form
others of the same bar
code symbology.
The unit powers up but
does not scan and/or
beep.
The unit beeps at some
bar codes but NOT for
others of the same bar
code symbology.
RS232 Only
The unit powers up OK
and scans OK but does
not communicate properly
to the host.
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.
