Title says it all..Eatlier this week it was intermittant...now wont come to ready. Error 938.30 "check weather station"..Per Lexmark, have reseated system board connectors, replaced external thermistor behind fuser, replaced fuser and re installed firmware. Now they want me to send $800.00 for new sys board.. ( Cant interchange boards from different machine supposedly )..Thought someone may have seen this error before. Insane. Lexmark support marginal at best on this). Is this error rare or common? I hope there are some Lexmark Guru's out there..
