How to troubleshoot no LEDs, beep, or laser on Metrologic MS9520 Barcode Reader?
If your Metrologic Barcode Reader isn't showing any LEDs, beeping, or emitting a laser, it might not be getting power. Check the transformer, outlet, and power strip. Also, ensure the cable is securely plugged into the scanner.
What to do if Metrologic Barcode Reader scans, but the data transmitted to the host is incorrect?
If the Metrologic Barcode Reader scans a bar code but the transmitted data is incorrect, verify that the scanner’s data format matches what the host system requires. Also, make sure the scanner is connected to the correct host port.
Why is Metrologic MS9520 transmitting each character twice?
If your Metrologic Barcode Reader is transmitting each character twice, try increasing the interscan code delay setting. Also, adjust whether the F0 break is transmitted; you may need to test both settings.
Why Metrologic MS9520 powers up, but does not scan and/or beep?
If your Metrologic Barcode Reader powers up but doesn't scan or beep, it could be due to scanning a symbology that isn't enabled. By default, UPC/EAN, Code 39, interleaved 2 of 5, Code 93, Code 128, and Codabar are enabled. Verify the barcode type you're trying to read is selected.
What to do if Metrologic Barcode Reader scans a bar code, but locks up after the first scan red LED stays on?
If the Metrologic Barcode Reader scans a barcode and then locks up with the red LED staying on, the scanner might be configured for host handshaking but isn't receiving the signal. If ACK/NAK, RTS/CTS, XON/XOFF, or D/E is set up, verify that the host cable and host support the handshaking properly.
What to do if Metrologic MS9520 Barcode Reader powers up, but does not scan and/or beep?
If your Metrologic Barcode Reader powers up but does not scan and/or beep, the scanner may be programmed for a character length lock, or a minimum length, and the barcode being scanned doesn't meet the programmed criteria. Verify that the barcode being scanned meets the criteria; the scanner defaults to a minimum of 3 characters for non-UPC/EAN codes.
Why does Metrologic MS9520 Barcode Reader unit scan, communicates and beeps twice?
If your Metrologic Barcode Reader scans, communicates, and then beeps twice, the 'same symbol timeout' might be set too short. Try adjusting it to a longer time.
Why The unit scans the bar code but there is no data from Metrologic MS9520?
If your Metrologic Barcode Reader scans a barcode but there is no data transmitted, ensure the scanner is configured for the appropriate mode.
Why The unit scans but the data is not correct from Metrologic MS9520 Barcode Reader?
If your Metrologic Barcode Reader scans but the data is not correct, make sure that the proper PC type (AT, PS2, or XT) is selected. Verify the correct country code and data formatting are selected, and adjust the inter-character delay symptom.
Why alpha characters show as lower case on Metrologic MS9520?
If the alpha characters appear as lower case on your Metrologic Barcode Reader, enable the Caps Lock detect setting of the scanner to detect whether the PC is operating in Caps Lock.
