Where is the circuit breaker located? I need to reset it.
The circuit breaker on my HP CP1215 tripped and I don’t remember where it is to reset it.
Questa è una buona domanda?

Hi Danny
From my understanding, I doubt there is any known reset breaker.
Based on the parts I see, there are 110V power supply parts and also 230V power supply parts.
110V

230V

In summary, due to wrong voltage,
Primary side of the power supply components has been damaged, e.g. bridge rectifier / transistor etc, so thats why when you on, your ELCB trips..
the only way is to remove the board and perform repair or replacement.
so when using 220V ..... you need to use a step down voltage transformer for this ...

Danny Ballard I am not familiar with any resettable breaker on this model. Let us know what your printer does, or does not do, so we can try to help you with it.

HP uses a linear supply on the LJ line—it's not an SMPS that can handle 100-240V global voltage. Were you trying to use a 120V printer on a 240V outlet? That's usually what causes this. Running 120V on a 240V power supply would create a brownout condition which CAN cause damage, but not in every instance.
The only way to use the 120V LJ printers on 240V is to swap the 120V fuser for a 240V one and the 120V power supply. If the printer has any secondary driver boards like the HVPS need to be swapped as well, but it's generally a fuser and LVPS/primary power supply swap.

Hi Danny
What has happened?
Had you tried with another power outlet?
is the side power switch in ON position?

@salmonjapan Yes I have tried several outlets. It is 110 voltage printer and was plugged into 220. It has done this before and I was able to reset it but I can't remember how I did it. I heard the circuit breaker trip when it was turned on.
