Motor Troubleshooting
The resistance values for the CR motor and the PF motor are given below, however, the values cannot be used to check the motors status since they are DC motor and the resistance between the electric poles varies. Visually check the motors for abnormal operation and if it is hard to judge, replace the motor.
Motor resistance and check point
  • CR motor
    Motor Type: DC motor with brush
    Drive Voltage: DC 42V ± 5%
    Resistance: 28.8Ω ± 10%
  • PF motor
    Motor Type: DC motor with brush
    Drive Voltage: DC 42V ± 5%
    Resistance: 21.2Ω ±10%
  • Scanner motor
    Motor Type: 2-phase, 96-pole PM stepping motor
    Drive Voltage: DC 42V ± 5%
    Resistance: 43.0Ω ± 10%
  • ADF motor
    Motor Type: PM stepping motor
    Drive Voltage: DC 42V ± 5%
    Resistance: 20.0Ω ± 7%
