voltage is distributed to the DC power supply circuitry and to the AC driver circuitry, which controls AC voltage to the fusing assembly's heating element. Fuse 102 (found only on 110V units) provides overcurrent protection to the printer DC power supply circuitry. q In addition, the +12V DC and +5V - HP 3150 | Service Manual - Page 73
applies a positive or negative DC voltage to the transfer roller according to the instructions from the ECU.
