Problem Possible Causes Possible Solutions
Nothing happens when
you follow the operating
instructions, or the
scanner displays erratic
behavior (laser does not
come on, scanner emits
frequent beeps). No power to the scanner. Check the system power. Ensure the
power supply is connected if your
configuration requires a power supply.
Interface/power cables are
loose. Check for loose cable connections.
Laser comes on, but
symbol does not decode. Scanner is not programmed
for the correct bar code type. Be sure the scanner is programmed to
read the type of bar code you are
scanning.
Bar code symbol is
unreadable. Check the symbol to make sure it is not
defaced. Try scanning test symbols of
the same bar code type.
Distance between scanner
and bar code is incorrect. Move the scanner closer to or further
from the bar code.
Symbol is decoded, but
not transmitted to the
host. Scanner is not programmed
for the correct host type. Scan the appropriate host type bar code.
