    Xerox wc 7556 speed mismatch

    Hello friends
    I have a xerox machine wc 7556, it shows SIM card insertion is required and registers a fault code 341-371 in diagnostics. Is there a way I can bypass the SIM card to make the machine work. Is there an NVM value that I any change to match the speed.
    Thanks

      Nope. What you are wanting to do is exactly what the SIM card is designed to prevent you from doing.

      Xerox implemented the SIM cards to prevent people from changing the speed of their machine, since mechanically they are often the same. It is a security measure, designed specifically to NOT be able to bypass.

      On a service contract, if the machine developed a problem, of course it would be taken care of under contract. Off-contract, unfortunately that type of error becomes much more of a problem, even when someone ISN'T trying to illegally bump up the speed of their machine. But then, if you are off-contract, Xerox isn't particularly concerned.

      Sorry...

          Hmm... I've got a Xerox WC7556 that works fine without the SIM card inserted. I have the SIM card saved in the paper drawer storage compartment, but it is not needed to be inserted. A Xerox tech (who was specifically trained on the WC7556) said the SIM is only necessary for initial machine config, then is no longer needed.

                  I am not sure about 7556 but open tray 1 and there might be a cover to remove and under it you may have your sim card there. I have seen a lot of time when engineers store sim card there. It is also worth to check tray 2 too.
