Scanner emits short low/short
medium/short high beep sequence. Scanner is powering up. Normal when scanner is plugged
in.
Nothing happens when scan trigger
is pressed. No power to the scanner. Check the system power. Ensure
the power supply is connected if
the configuration requires a power
supply.
Power supply is not plugged in.
Incorrect host interface cable is
used. Ensure that correct host interface
cable is used.
Interface/power cables are loose. Ensure all cable connections are
secure.
Scanner is disabled. For Simple Serial Interface (SSI),
enable the scanner via the host
interface. Otherwise, see the
technical person in charge of
scanning.
If using RS-232 Nixdorf B mode,
CTS is not asserted. Assert CTS line.
Scanner emits short low/short
medium/short high beep sequence
more than once. The USB bus may put the scanner
in a state where power to the
scanner is cycled on and off more
than once. Normal during host reset.
Laser comes on, but scanner does
not decode the bar code. Scanner is not programmed for the
correct bar code type. Ensure the scanner is programmed
to read the type of bar code being
scanned.
Bar code symbol is unreadable. Check the symbol to ensure it is not
defaced. Try scanning test bar
codes of the same bar code type.
See
Appendix C, Sample Bar Codes
for test bar codes.
Bar code is out of range from the
scanner. Move scanner closer to or further
from bar code.
