Possible solutions
Nothing happens when you
follow the operating instructions,
or the scanner displays erratic
behavior.
No power to the scanner.
Check the system power. Ensure the
power supply is connected.
Incorrect cables.
Use the original cables.
Connections are loose.
Check for loose cable connections.
Laser comes on, but the scanner
does not decode.
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.
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.
