Symptoms Possible Causes Solution
The unit powers
up, but does not
scan and/or
beep.
The unit is trying to
scan a particular
symbology that is
not enabled.
UPC/EAN, Code 39,
interleaved 2 of 5,
Code 93, Code 128
and Codabar are
enabled by default.
Verify the type of
bar code being
read has been
selected.
The unit powers
up, but does not
scan and/or
beep.
The bar code being
scanned does not
satisfy the con-
figured criteria for
character length
lock or minimum
length.
Verify the bar code
being scanned falls
into the configured
criteria. The scanner
defaults to a mini-
mum of three-
character bar code.
TTL RS232 & Serial Emulation USB Interfaces
The unit scans
a bar code, but
locks up after
the first scan
and the red LED
stays on.
The unit is con-
figured to support
some form of host
handshaking but is
not receiving the
signal.
If the unit 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 unit’s data
format does not
match the host
system’s
requirements.
Verify the unit’s data
format matches that
required by the host.
Make sure that the
unit is connected to
the proper host port.
The bar code may
have been printed
incorrectly.
The unit is not
configured correctly
for the type of bar
code being scanned.
Check if it is a
check digit/
character/or border
problem.
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.
Keyboard Wedge Interface
The unit scans
the bar code but
there is no data.
The unit’s
configuration is not
correct.
Make sure the scanner
is configured for the
appropriate mode.
