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.

Check the symbol to make sure it is not

defaced. Try scanning test symbols of the

same bar code type.

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.
