If the barcode is not recognized by Dynamsoft Barcode Reader, please do not hesitate to contact Dynamsoft support team.

Alternatively, here is the general troubleshooting steps:

  1. Please ensure the lighting is not very bright or very dim.
  2. Please ensure the aimming barcode format has been checked on.(Advanced Scan -> settings -> Barcode Format -> check the barcode formats)
  3. We can decrease the Confidence level to increase the read rate.(Advanced Scan -> settings -> Result Settings -> Set Confidence Level to 10)
  4. We can increase the deblur level to increase the read rate.(Advanced Scan -> settings -> Additional Settings -> increase DeblurLevel)
