Product: HP PRO 4303FDW MFP LASER

I need technical assistance for my HP PRO 4303FDW printer in São Paulo, Brazil. Can anyone recommend one?

 

Our printer has a voltage of 110V and was connected to 220V.

 

The diagnosis is to replace the RM3-7530 power supply board. However, this must be done at an authorized HP partner company, which we did not find on any list on the HO or Simpress.com.br websites.

 

Can anyone recommend a list of authorized HP technical support centers to replace this power supply board?

Simply replacing the power supply will not make a 110V printer a 220V printer. The fuser unit is powered directly off the mains as well so it would need to be replaced.
