The ac line power is directed through the power switch, noise filter, and
CB101. From CB101 the ac line power is directed to the LVPSA and to the
fixing heater circuits.
The following serial devices control the fixing heater current:
• Relay RL01 is operated by the safety circuit.
• The solid state relay (SSR) is operated by the dc control board.
• The thermoprotection (TP1) switch is actuated directly by the heat
coming off the fixing heat roller.
