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. Sc anner is not programm ed
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.
