• Code: 396
• Description: Black drum motor error
• Causes: The LOCK signal error is detected when the EGB monitors the black drum motor state. (This monitoring is done immediately after power-on, when the motor starts rotating, and immediately after the motor stops.)
• Remedy: • Disconnected or defective motor harness. • Motor slips due to excessive load 1. Check the harness from the black drum motor. Replace it if necessary.e hig

• Code: 397
• Description: Color drum motor error
• Causes: The LOCK signal error is detected when the EGB monitors the color drum motor state. (This monitoring is done immediately after power-on, when the motor starts rotating, and immediately after the motor stops.)
• Remedy: • Disconnected or defective motor harness. • Motor slips due to excessive load 1. Check the harness from the color drum motor. Replace it if necessary.

• Code: 400
• Description: TM sensor error
• Causes: The CPU detected a low voltage of the positive reflection output under the threshold in the TM sensor.
• Remedy: • TM sensors are dirty. • A solid print out due to an electrostatic charging error • The TM sensor is defective. 1. Clean the TM sensors. 2. Replace the TM sensors. 3. Check the image transfer unit. 4. Turn the power Off and On.

• Code: 445
• Description: ITB (Image Transfer Belt) Unit: Home Position Error
• Causes: The ITB contact sensor does not detect the home position of the ITB for 5 seconds after the ITB unit initialization has been done. ITB (Image Transfer Belt) Unit: Contact Position Error The ITB contact sensor does not detect the contact position of the ITB for 5 seconds after the ITB unit has moved to the contact position. ITB (Image Transfer Belt) Unit: No-contact Position Error The ITB contact sensor does not detect the home position of the ITB for 5 seconds after the ITB unit has moved to no-contact position.
• Remedy: • Defective ITB contact motor • Defective ITB contact sensor • Defective ITB unit 1. Replace the ITB contact motor. 2. Replace the ITB contact sensor. 3. Replace the ITB unit.

• Code: 480
• Description: Agitator Motor Error
• Causes: The agitator motor error is detected twice for 10 msec during the initialization at power-on or after the cover is closed.
• Remedy: • Disconnected or defective harness • Defective agitator motor 1. Check or replace the harness. 2. Replace the agitator motor.

• Code: 490
• Description: ITB (Image Transfer Belt) Unit Set Error
• Causes: The TM sensor does not detect the reflection from the ITB.
• Remedy: • No ITB unit in the machine • Dirty TM sensor 1. Check the installation of the ITB unit. 2. Clean the TM sensor.S

• Code: 500
• Description: Transport/Fusing Motor Error
• Causes: The LOCK signal error is detected when the EGB monitors the transport/fusing motor state. (This monitoring is done immediately after power-on, when the motor starts rotating, and immediately after the motor stops.)
• Remedy: • Disconnected or defective motor harness. • Motor slips due to excessive load 1. Check the harness from the transport/fusing motor. Replace it if necessary.

• Code: 530
• Description: LSU Fan Motor Error
• Causes: A LOCK signal is not detected for more than ten seconds while the motor START signal is on and if this error occurs twice consecutively, this SC is issued.
• Remedy: • Disconnected or defective motor harness. • Defective LSU fan motor 1. Check or replace the motor harness. 2. Replace the LSU fan motor.
