Hi,
ive got a sharp mxm850 showing h2-00 error. Error relates to non contact thermistor open error. I've checked continuity of lamps and the two thermostats. Both fine. The connections of the fuser unit and the connectors at the back of the machine are fine. The code can be reset using sim 14 but returns as soon as the fuser unit is in place and the front door closes. There is no attempt to warm up, the code just instantly comes on. Do you think it's a simple case of replacing the non contact thermistor? The machine has done 4.5 million with the original fuser unit.
thanks in advance
