    F070

    I have an es4520c that is working fine. I installed a used fax and when I turned it on it came up with the code f070. When I unplugged the fax it runs fine. I am pretty sure it is either the fax or ribbon. Before I have another fax over nighted is there a chance it could be the system board. Any thought would be appreciated.

    What is your fax kit? GD-1250 or 1260?
    Fax kit setup should help you

      F070 is a communication error between LGC and SYS bds. Check both for latest versions . Lgc is V.21 and Sys. Ver. 331.
      It could be a bad fax bd causing the sys not to see the lgc bd.
