Symptoms Possible

Causes

Solution

Unit scans,
Communicates
and beeps twice

Same symbol timeout
set too short

Adjust same symbol timeout for a
longer time.

The unit powers
up, but does not
scan/or beep

Beeper disabled. No
tone selected

Enable beeper. Select tone.

The unit powers
up, but does not
scan and/or
beep

Scanning 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 that the type of bar code
being read has been selected.

The unit powers
up, but does not
scan and/or
beep

The scanner has
been programmed for
a character length
lock, or a minimum
length and bar code
being scanned does
not satisfy the
programmed 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 3-character bar code.

The unit scans
a bar code, but
locks up after
the first scan
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. Most sure that the
scanner is connected to the
proper host port.

Scanner beeps
at some bar
codes and NOT
for others of the
same bar code
symbology

The print quality of
the bar code is
suspect

Check print mode. The type of
printer could be the problem.
Change print settings. i.e. change
to econo mode or high speed.
