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. See Symbologies.
|
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.
See Decode Ranges. | |
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. | Scan Default Parameters. |
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. |
