TROUBLESHOOTING
Symptom Possible Cause(s) Solution
All Interfaces
The unit scans a bar
code, but locks up after
the first scan (the white
LED stays on).
The scanner is
configured to support
some form of host
handshaking but is not
receiving the signal.
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.
The unit scans but the
data transmitted to the
host is incorrect.
The scanner’s data
format does not match
the host system
requirements.
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 print quality of the
bar code is suspect.
Check the character
length lock.
Scanner beeps at some
bar codes and NOT
from others of the same
bar code symbology.
The aspect ratio of the
bar code is out of
tolerance.
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.
The unit is trying to
scan a particular
symbology that is not
enabled.
UPC/EAN and Code 128 are enabled by default. Verify that the type
of bar code being read has been selected.
The unit powers up but
does not scan and/or
beep.
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.
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.
The bar code may have
been printed incorrectly. Check if it is a check digit, character or border problem.
The scanner is not
configured correctly for
this type of bar code.
Check if check digits are set properly.
The unit beeps at some
bar codes but NOT for
others of the same bar
code symbology.
The minimum symbol
length setting does not
work with the bar code.
Check if the correct minimum symbol length is set.
