how to get the NEC scanner to scan continuously

For most NEC barcode scanners, you switch the scan mode to continuous through the scanner’s configuration barcodes or setup utility, not just by holding the trigger. Manufacturer documentation for similar scanners shows a “Continuous Mode” setting where the scanner keeps scanning until the scan completes or times out, and some models also have an auto-sensing or toggle mode instead.

What to try

1. Find the scanner’s manual or setup sheet for your exact NEC model.
2. Look for settings named Continuous Mode , Auto Sensing Mode , or Toggle Mode.
3. Scan the programming barcode for Continuous Mode if your model uses barcode setup.
4. If it uses software setup, change the reading mode in the utility and save the settings.
5. Reboot the scanner if the manual says settings only take effect after power cycling.

Important detail

Some scanners in continuous mode keep the light on and scan repeatedly until no barcode is detected or a timeout occurs, while others use a trigger-based continuous auto-off mode instead. If you’re seeing only one scan per trigger pull, your device may be in toggle or single-read mode rather than true continuous mode.
