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 unit scans a bar
code, but locks up
after the first scan
(the blue 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.
