This machine had an H2 00 problem , pulled the fuser , cleaned the thermistor , metered it , a little over 200k ohms cold . Reassembled and attempted to enter the service mode to do reset , # , Interrupt , C , Interrupt , but not happening . Pulled the op panel and metered the push button switches , they all seemed OK , maybe need to resolder the switches I suppose , did not have my iron . Any other thoughts here ? Never have seen but this one of this model . Thanks in advance , Ark .
