Thermistor fuse Toshiba e-studio 232
There are only themostat and themistor on the fuser unit.
If C440 sign on frequently, probably the themistor is deformed, which need to be replaced.
For 1st C440 sign on, try to reset it by entering 08-400, change the value appear on screen to "0", then reboot machine, if the machine is working, just leave it.
If not, C440 will sign on again, then only u replace the themistor.
To replace it very simple, take out the fuser unit, reverse it, and u will see a black plastic compartment, open it up, and u will see the themistor.
