Re: MPC2051 SC 542

The statement "the following SPs below are designed for the factory use only", means that these are set at the factory by factory engineers. Unless you are a factory engineer and are doing a factory setup in a controlled environment, do not mess with them unless directed to do so by a factory engineer. They are not necessarily the same on all units. If the factory engineers decide that a settings need to be set to something different from the default, as indicated by their test equipment and procedures, they will adjust as needed. That is why each machine has a "Birth Certificate". If you still have the BC, set every according to it, otherwise leave them alone.

SP1-132-012 is the reference voltage. it is obvious that I can not change, but because it gives me 5 volts when it should be 220 volts?
On all other machines this vaolre and about 220 volts.

Re: MPC2051 SC 542

is it giving you that voltage because it cut power to the fusing unit due to the SC, is the SC gone and your not fusing or is the code still up. If its coded currently the voltage reference may not matter at all currently until you clear the code with 5810 and reset it. That or try another fusing unit and reset the code.

Hi, I do the situation:
This machine works regularly for several days, then suddenly it comes out that I reset SC 542 and go on for another day.
I replaced GROUP OF FUSER and Pila thermoelectric but the problem remained.
What I noticed is precisely that SP1-132-012 that is not the norm as other MP C2551 namely 1) on this machine gives me 5 volts, while the other varies from 220 to 230 volts.
All other recommendations have already been put into practice.

Did you replace Aw100138 thermopile this is not on the fuser its located inside the fuser cavity on the machine. I have only had to replace 1 once and it was doing like you said would work for a few days then come back shortly.
