Scanning Problems

What If ...

Nothing happens when you follow the operating instructions?
• Check the system power.
• Make sure the scanner is programmed to read the symbology you are trying to
read.
• Check the bar code to make sure it is not defaced. A defaced 1-D bar code may
not be readable by any scanner. Likewise, if a PDF417 symbol is damaged
beyond its error correction capability, it will not decode.
• Check to see if you are scanning from the proper distance.
• Try scanning a test symbol of the symbology you are trying to read.
Your terminal operates but scanned data is not displayed
correctly?
• Check the system power.
• Check that the communication parameters (baud rate, parity, stop bits, etc.) are
set properly for the receiving device.
The laser does not activate?
• You may have exceeded the allowable amount of scanning activity within the
limits of your laser class of operation; in this case, wait for a short interval until
scanning can resume.
• You may be scanning in an inappropriately hot environment. If so, remove the
equipment from that environment, or allow the laser to cool down.
