544 A Fusing overheat error 2


Is the machine plugged into an unstable supply?

[ponto700]

i know they connect the machine direct to the plug without any power supply... but when we advice them to use a power supply they dont buy becouse the stories are all the same: we dont have money for that. and then the problem is always from the machine! what is your sugestion TonerMunkeh?

today i change the 2 thermistors and the thermostats.. hope in next 30 days i dont have the same problem again.
thanks TonerMunkeh

A line filter/power supply is probably the best fix. if you have another fusing unit you could swap for a test and the same thing happens, it would point to a power problem. in all of the fuser codes i have seen, i think that have have only seen one with a bad power supply(TRIAC).
