Possible Causes
The scanner is
configured to support
some form of host
handshaking but is
not receiving the
signal.
The scanner's data
format does not
match the host
system requirements.
The print quality of
the bar code is
suspect.
The aspect ratio of
the bar code is out of
tolerance.
The bar code may
have been printed
incorrectly.
The scanner is not
configured correctly
for this type of bar
code.
The minimum symbol
length setting does
not work with the bar
code.
Inter-character delay
needs to be added to
the transmitted output
Solution
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.
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.
Check the print mode. The type of
printer could be the problem.
Change the print settings (i.e.
change to econo mode or high
speed).
