    The temp sensors usually cause this code but before you replace them, make sure you have the correct upper roller fitted. I chased this problem on a 420 for ages before I realised a previous tech had fitted a 500 roller!!
    Hope this helps..

      code

      I had the same problem when web roller was finished.
      But after I changed the web roller-code reappears .
      So,check the web roller. If it's ok - change :FIXING SENSOR ASSY
