Troubleshooting
Problem Possible causes Possible solutions
No power to the
scanner. Check the system power. Ensure the power
supply is connected.
Incorrect cables. Use the original cables.
Nothing happens when you
follow the operating
instructions, or the scanner
displays erratic behavior.
Connections are loose. Check for loose cable connections.
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.
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.
Laser comes on, but the
scanner does not decode.
Distance between
scanner and bar code
is incorrect. Move the scanner closer to or further from the
bar code.
Scanned data is incorrectly
displayed on the host. Scanner is not
programmed to work
with the host. Check
scanner host type
parameters or editing
options. Be sure proper host is selected.
For RS-232, ensure the scanner’s
communication parameters match the host’s
settings.
For a USB-HID keyboard or a keyboard
wedge configuration, ensure the system is
programmed for the correct keyboard type and
language, and the CAPS LOCK key is in the
correct state.
Other circumstances. Contact your distributor or the manufactory
support centre.
