bol does not
decode.

decoded,
but not
transmitted
to the host.

data is incor-
rectly dis-
played on
the host.
Possible
Cause
Scanner is not
programmed
for the correct
bar code type.
Bar code sym-
bol is unread-
able.
Distance be-
tween scanner
and bar code is
incorrect.
Scanner is not
programmed
for the correct
host type.
Scanner is not
programmed to
work with the
host. Check

rameters or ed-
iting options.
S e r i e s
Be sure the scanner is
programmed to read
the type of bar code
you are scanning.
Check the symbol to
make sure it is not de-
faced. Try scanning
test symbols of the
same bar code type.
Move the scanner
closer to the bar code.
Scan the appropriate
host type bar code.
Be sure proper host is
selected.
For RS-232, ensure
the scanner's com-
munication parame-
ters match the host's
settings.
For a keyboard
wedge configuration,
ensure the system is
programmed for the
correct keyboard
type, and the CAPS
LOCK key is off.
Be sure editing op-
tions (e.g., UPC-E to
UPC-A Conversion)
are properly pro-
grammed.
