SMPS & HVPS
It is the power supply for the entire system. It is assembled as an independent module, so it is
possible to use for common use. It is mounted at back of the machine. Power part is divided by
two independent PBAs - SMPS PBA and HVPS PBA. SMPS PBA supplies the DC power for driv-
ing the system and supplies the AC power to the fuser.
SMPS has two output channels: +5V and +24V. HVPS PBA supplies High voltage to the develop-
er part to make a printing image on the paper. High voltages applied to the MHV, THV, DEV, SUP-
PLY.
