  • Page 45: Power Supply Voltage Detection

    Power supply voltage detection The power supply voltage detection controls the fuser properly according to the voltage. The DC controller detects whether the low-voltage power supply voltage is 100V or 220V, according to the POWER SUPPLY VOLTAGE signal (/PSTYP100). Sleep mode The Sleep mode reduces the power consumption of the product.

  • Page 50: Fuser Temperature Control

    Fuser temperature control The fuser temperature control maintains the temperature of the fuser heater at its targeted temperature. The DC controller monitors the FUSER TEMPERATURE signals (MFSRTH, S1FSRTH, S2FSRTH and S3FSRTH), and sends the FUSER HEATER CONTROL signals (FSRD1 and FSRD2). The fuser heater control circuit controls the fuser heater depending on the signals, so that the fuser heater remains at the targeted temperature.
  • Page 51: Fuser Failure Detection

    Fuser failure detection The DC controller determines if the fuser functions properly.
