Why Honeywell Quantum T 3580 Barcode Reader unit has no LEDs, beeper or motor spin?

The Honeywell Barcode Reader might not have LEDs, beeper, or motor spin due to several reasons. It could be that no power is being supplied to the scanner, so check the transformer, outlet, and power strip, and ensure the cable is plugged into the scanner. Alternatively, some host systems might not supply enough current, so use the power supply included with the scanner. Other potential causes include a too-short 'same symbol timeout' (adjust it for a longer increment), a disabled beeper (enable it), no tone selected (select one), the bar code type not being selected (verify selection), or the scanner being configured for a character length lock or minimum length that isn't met (verify the bar code meets the criteria).
