    Is the replace master roll light flashing or solid on?? If it is flashing, it's saying get ready to replace. If it's on, then replace.
    OR is some other light on that your are confused with?
    Good luck.

    The 4 light has nothing to do with needing to replace the master roll. If the 4 light is on, then the master making unit is not set, there is a jam in the master making unit or some other error. But since you said you have no other lights or codes then see about the latch for the master making unit. If you have the service manual look into the master making section and maker making unit detection. If you don't have one, get one.
    Good luck.

    Either something is blocking the master end sensor or that senor board has gone bad. Open up the made making unit and look at the sensor. Get a manual and go into test mode and check the sensor in test mode. If you can not get a service manual, have certified technician work on it.
    Good luck.
