Power-save mode The power-save mode reduces product power consumption. When the power supply unit receives the power save (PSREM24V) signal from the DC controller, it stops the power supply from the +24V generation circuit. Fuser control The power supply unit controls the temperature in the fuser - HP Color LaserJet CM2320 | Service Manual - Page 101
