If, after performing the possible solutions in the following table, the scanner still experiences problems, contact the distributor or call support.
Troubleshooting
Problem
Possible Cause
Possible Solution
The illumination does not appear when pressing the trigger.
No power to the scanner.
If the configuration requires a power supply, re-connect the power supply.
Incorrect host interface cable is used.
Connect the correct host interface cable.
Interface/power cables are loose.
Re-connect cables.
Scanner is disabled.
For IBM 468x and USB IBM hand-held, IBM table-top, and OPOS modes, enable the scanner via the host interface. Otherwise, see the technical person in charge of scanning.
If using RS-232 Nixdorf B mode, CTS is not asserted.
Assert CTS line.
Scanner emits illumination, but does not decode the barcode.
Scanner is not programmed for the correct barcode type.
Program the scanner to read that type of barcode.
Barcode symbol is unreadable.
Scan test symbols of the same barcode type to determine if the barcode is defaced.
The symbol is not completely inside illumination.
Move the symbol completely within the illumination. Move the symbol completely within the field of view (AIM pattern does NOT define FOV).
Distance between scanner and barcode is incorrect.
Move the scanner closer to or further from the barcode.
Scanner decodes barcode, but does not transmit the data to the host.
Scanner is not programmed for the correct host type.
Scan the appropriate host type programming barcode. See the chapter corresponding to the host type.
Interface cable is loose.
Re-connect the cable.
If the scanner emits four long low beeps, a transmission error occurred. This occurs if a unit is not properly configured or connected to the wrong host type.
Set the scanner's communication parameters to match the host's setting.
If the scanner emits 5 low beeps, a conversion or format error occurred.
Configure the scanner's conversion parameters properly.
If the scanner emits low/high/low beeps, it detected an invalid ADF rule.
Program the correct ADF rules. Refer to the Advanced Data Formatting Programmer Guide.
Host displays scanned data incorrectly.
Scanner is not programmed to work with the host.
Scan the appropriate host type programming barcode.
For RS-232, set the scanner's communication parameters to match the host's settings.
For a Keyboard Wedge configuration, program the system for the correct keyboard type, and turn off the CAPS LOCK key.
Program the proper editing options (for example, UPC-E to UPC-A Conversion).
Scanner emits short low/short medium/short high beep sequence (power-up beep sequence) more than once.
The USB bus may put the scanner in a state where power to the scanner is cycled on and off more than once.
Normal during host reset.
Scanner emits 4 short high beeps during decode attempt.
Scanner has not completed USB initialization.
Wait several seconds and scan again.
Scanner emits Low/low/low/extra low beeps when not in use.
RS-232 receive error.
Normal during host reset. Otherwise, set the scanner's RS-232 parity to match the host setting.
Scanner emits low/high beeps during programming.
Input error, incorrect barcode or Cancel barcode was scanned.
Scan the correct numeric barcodes within range for the parameter programmed.
Scanner emits low/high/low/high beeps during programming.
Out of host parameter storage space.
Out of memory for ADF rules.
Reduce the number of ADF rules or the number of steps in the ADF rules.
During programming, indicates out of ADF parameter storage space.
Erase all rules and re-program with shorter rules.
Scanner emits low/high/low beeps.
ADF transmit error.
Refer to the Advanced Data Formatting Guide for information.
Invalid ADF rule is detected.
Refer to the Advanced Data Formatting Guide for information.
Scanner emits a power-up beep after changing USB host type.
The USB bus re-established power to the scanner.
Normal when changing USB host type.
Scanner emits one high beep when not in use.
In RS-232 mode, a <BEL> character was received and Beep on <BEL> option is enabled.
Normal when Beep on <BEL> is enabled and the scanner is in RS-232 mode.
Scanner emits frequent beeps.
Inadequate power supplied to the scanner.
Check the system power. If the configuration requires a power supply, re-connect the power supply.
Incorrect host interface cable is used.
Verify that the correct host interface cable is used. If not, connect the correct host interface cable.
Interface/power cables are loose.
Check for loose cable connections and re-connect cables.
Scanner emits five long low beeps after a barcode is decoded.
Conversion or format error was detected. The scanner conversion parameters are not properly configured.
Ensure the scanner conversion parameters are properly configured.
Conversion or format error was detected. An ADF rule was set up with characters that cannot be sent for the host selected.
Change the ADF rule, or change to a host that can support the ADF rule.
Conversion or format error was detected. A barcode was scanned with characters that cannot be sent for that host.
Scan a different barcode, or change to a host that can support the barcode.
The -08 model emits a low-high-high-low beep sequence (may sound once every 10 seconds)
The attached aux scanner is drawing to much current.
Disconnect/Reconnect the aux scanner. If that doesn’t solve the issue replace the aux scanner.
Scanner emits a high, low beeper sequence.
An unsupported USB device was plugged into the USB host port, and/or the device failed enumeration.
Disconnect the unsupported device.
