Error Code E004 on Canon NP 6330

[mzole]

Hey out there!
I have been experiencing the above mentioned error on my copier machine.At first I thought it has to do with the heater lamps but after changing them still the error code was there, then i replaced the Thermistor and Thermostat respectively but still it was the same.
Then I tried a new mainboard( DC Controller) to my suprise the error became 001, and I decided to put the old board back.
So my question is what could be the cause of the problem? somebody mentioned to me that it could be to fauly SSR Unit.Could this be the case?
