If powering the printer off and on doesn't clear this error code then service is needed. Please call into the support department at 1-800-835-6100 to schedule a service request.
I installed the bridge firmware 64.59.11 (Bridge Release) and now am getting Error 043-342 which states to power OFF and then ON. I have tried several times, including unplug overnight and error remains.
I cannot reach admin menu due to this and thus cannot even try a factory reset. A search in the forum shows that someone else had this error on a different machine and that firmware fixed it but doesn't state how they achieved it.
