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