• Code: SC492-00
• Description: High voltage power source: image transfer/paper transfer: output error SC detection signal (transfer) is L (abnormal) for 200 ms consecutively during high voltage (transfer) output.
• Causes: H/W error • Output power connector setting fault • Controller connector setting fault • Output high voltage Harness disconnection • Controller harness disconnection, short-circuit • Transfer unit setting fault • Control board_ IOB error (related signal error) • HVP_TTS error Load error • Increase in paper transfer roller impedance (low temperature environment/impedance rise/impedance rise due to dirt) • Operation fault of paper transfer contact mechanism • Increase in image transfer belt impedance • Opening in load power supply path
• Remedy: • Reset or replacement the harness of high voltage power supply feed path • Reset or replace the harness between IOB-HVP_TTS • Reset or replace the transfer unit • Check operation of the contact mechanism • Replace the HVP_TTS • Replace the IOB

• Code: SC493-00
• Description: High voltage power source: DS development: output error "HVP:DS:output error detection signal" is detected “0” (abnormal) for 10 times consecutively (for 200ms) during output of the PWM signal used as an error detection target
• Causes: • Leak harness fault • Unit fault • High voltage power source fault
• Remedy: • Turn the power off/on • Reset or replacement the harness of high voltage power supply feed path • Reset or replace the unit • Replace the high voltage power source

• Causes: • Connector disconnection or broken • Sensor defective
• Remedy: • Check the sensor setting • Replace the imaging temperature sensor (thermistor)

• Code: SC498-00
• Description: Temperature and humidity sensor error Temperature sensor output error: Below 0.76V, or above 2.90V, or Moisture sensor output error: more than 2.4V
• Causes: • Sensor not setting (disconnection or broken) • Sensor defective
• Remedy: • Check the sensor setting • Replace the sensor
