   Does your scanner give real time data?   
      
   Most scanners, all cheaper ones, only give the scan code, which you   
   have.   
      
   Look it up online, see what it means, and see what remedies are   
   suggested for it.   
      
   That will probably go faster than using the scanner even if it does give   
   real-time data.
