SYMPTOMS
POSSIBLE
CAUSE(S)
SOLUTION
The unit beeps for
some bar codes
and NOT for
others of the same
bar code
symbology.
The bar code may
have been printed
incorrectly.
Check if it is a check digit/character/or border problem.
The scanner is not
configured correctly
for the type of bar
code.
Check if the check digits are set properly.
The minimum symbol
length setting does
not work with the bar
code.
Check if the correct minimum symbol length is set.
The unit is not
transmitting each
character.
The configuration is
not set correctly.
Increase the interscan code delay setting. Adjust if the F0
break is transmitted. It may be necessary to try this in both
settings.
Alpha characters
show as lower
case.
The computer is in
Caps Lock mode.
Enable the Caps Lock detect setting of the scanner to detect
whether the PC is operating in Caps Lock.
Power-up OK and
scans OK but
does not
communicate
properly to the
host.
Com port at the host
is not working or
configured properly.
Check to make sure that the baud rate and parity of the
scanner and the communication port match and the program is
looking for “RS-232" data.
Com port not
operating properly.
Cable is not
connected to the
proper com port.
The host is receiving
data but the data
does not look
correct.
The scanner and
host may not be
configured for the
same interface font.
Check that the scanner and the host are configured for the
same interface font.
Characters are
being dropped.
Intercharacter delay
needs to be added to
the transmitted
output.
Add some intercharacter delay to the transmitted output by
using the MetroSelect Configuration Guide (
MLPN 00-02407).
