• Code: 460-00
• Description: Separation: Output error
  The "HVP_ERR_D output error Sensor signal" is monitored at 20 ms intervals. If 0 (error) is detected ten times in succession (200 ms), the following causes are suspected:
• Causes: • Transfer Roller error • High Voltage Power Supply (Separation) error • Damaged HVP connection harness
• Remedy: • Replace the Image Transfer Roller. • Replace the High Voltage Power Supply (Separation) • Replace the harness.

• Code: 490-00
• Description: Charging/developing: Output error
  The "HVP_ERR1: Output error Sensor signal" is monitored at 20 ms intervals. If 0 (error) is detected ten times in succession (200 ms), the following causes are suspected:
• Causes: • Failed PCDU • Failed High Voltage Power Supply (Separation) • Damaged HVP connection harness
• Remedy: • Repalce the PCDU. • Replace the HVP. • Replace the harness.

• Code: 491-01
• Description: Primary/secondary transfer: Output error
  The "HVP_ERR2: Output error Sensor signal" is monitored at 20 ms intervals. If 0 (error) is detected ten times in succession (200 ms) (during bias output), the following causes are suspected:
• Causes: • Image Transfer Unit error • Transfer Roller error • Damaged HVP connection harness • Noise generated by poor contact of the power supply terminals of the Development Roller
• Remedy: • Replace the Image Transfer Unit. • Replace the Transfer Roller • Replace the HVP. • Replace the harness. • Replace the PCDU.

• Code: 491-02
• Description: Disconnected connector: High voltage output error
  The "HVP_ERR2: Output error Sensor signal" is monitored at 20 ms intervals. If 0 (error) is detected ten times in succession (200 ms) (during non-bias output), the following causes are suspected
• Causes: • HVP Connect harness disconnected • Damaged HVP connection harness
• Remedy: • Check the HVP Connect harness • Replace the HVP connection harness.

• Code: 498-00
• Description: Temperature/humidity Sensor error
  • Temperature Sensor output error: Out of range between 076 V and 2.90 V • Humidity Sensor output error: 2.4 V or more
• Causes: - Unmounted Sensor (Unset connector or broken wire) - Failed Sensor
• Remedy: • Turn the power OFF and then ON. • Check that the connector is set. • Replace the Sensor. • Replace the connector.

• Code: 508-00
• Description: By-pass bottom plate operation error
  The signal from the by-pass bottom plate position Sensor has not changed (that is, the signal has not changed from ON to OFF or vice versa) for two seconds or more after the start of reverse Paper Feed Unit rotation, If the error is detected three times in succession, the appropriate SC number is displayed on the operation panel unit.
• Causes: - By-pass bottom plate Sensor connector disconnected or other error - By-pass bottom plate Sensor feeler stuck or other error
• Remedy: • Turn the power OFF and then ON. • Check and replace the by-pass bottom plate Sensor connector connection. • Replace the by-pass bottom plate Sensor feeler. • Replace the Paper Feed Motor.

• Code: 520-02
• Description: Fusing motor error Early Detection
  • A command to stop the rotation of the motor has been issued right after the power was turned on, but the motor is still rotating. Motor Operation Timing • When the motor rotation request or speed change request is issued, the motor is in the stopped state. Motor Stop Timing A command to stop the rotation of the motor has been issued, but the motor is still rotating.
• Causes: - Disconnected connector - Broken signal wire - Excessive motor torque
• Remedy: - Check the connector connection. - Turn the power OFF and then ON. - Replace the Fusing Motor.

• Code: 521-01
• Description: Bank 1 motor error (Bank: paper tray unit)
  Early Detection • A command to stop the rotation of the motor has been issued right after the power was turned on, but the motor is still rotating. Motor Stop Timing A command to stop the rotation of the motor has been issued, but the motor is still rotating.
• Causes: - Disconnected connector - Broken signal wire - Excessive motor torque
• Remedy: - Check the connector connection. - Turn the power OFF and then ON. - Replace the bank 1 motor.
