Decoding Bar Codes
Scanner emits the laser, but
does not decode the bar
code. Scanner is not programmed for the
correct bar code type. Program the scanner to read that type of bar
code. See
Chapter 12, Symbologies .
Bar code symbol is unreadable. Scan test symbols of the same bar code
type to determine if the bar code is defaced.
Distance between scanner and bar
code is incorrect. Move the scanner closer to or further from
the bar code. See LS4208 Decode Zone on
page 2-11.
The scan line is not crossing every
bar and space of the symbol. Move the symbol until the scan line is within
the acceptable aiming pattern. See
Figure
2-6 on page 2-6 .
Scanner decodes bar code,
but does not transmit the
data to the host. Scanner is not programmed for the
correct host type. Scan the appropriate host type
programming bar code. See the chapter
corresponding to the host type.
Interface cable is loose. Check for loose cable connection and
re-connect cable.
Scanner emits five long low
beeps after a bar code is
decoded. Conversion or format error was
detected.
The scanner’s conversion
parameters are not properly
configured.
Ensure the scanner’s conversion
parameters are properly configured.
Conversion or format error was
detected.
An ADF rule was set up with

host selected.
Change the ADF rule, or change to a host
that can support the ADF rule.
Conversion or format error was
detected.
A bar code was scanned with
characters that can't be sent for that
host.
Change the bar code, or change to a host
that can support the bar code.
