• Code: 195
• Description: Serial Number Error
  The serial number stored in the memory (EGB) is not correct.
• Causes: EEPROM defective. EGB replaced without original EEPROM.
• Remedy: 1. Check the serial number. 2. If the stored serial number is incorrect, contact your supervisor.

• Code: 300
• Description: High voltage power output error
  The measured voltage is not correct when the EGB measures each charge output (charge, development, image transfer belt unit, and transfer unit).
• Causes: Disconnected or defective high voltage harness. Defective high voltage power supply. Defective EGB.
• Remedy: 1. Check or replace the harnesses. 2. Replace the high voltage power supply board 3. Replace the EGB.

• Code: 396
• Description: Black drum motor error
  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.)
• Causes: Disconnected or defective motor harness. Motor slips due to excessive load.
• Remedy: 1. Check the harness from the black drum motor. Replace it if necessary.

• Code: 397
• Description: Color drum motor error
  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.)
• Causes: Disconnected or defective motor harness. Motor slips due to excessive load.
• Remedy: 1. Check the harness from the color drum motor. Replace it if necessary.

• Code: 445
• Description: ITB (Image Transfer Belt) Unit Error
  Home Position Error 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.
• Causes: Defective ITB contact motor. Defective ITB contact sensor. Defective ITB unit.
• Remedy: 1. Replace the ITB contact motor. 2. Replace the ITB contact sensor. 3. Replace the ITB unit.

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

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

• Code: 500
• Description: Transport/Fusing Motor Error
  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.)
• Causes: Disconnected or defective motor harness. Motor slips due to excessive load.
• Remedy: 1. Check the harness from the transport/fusing motor. Replace it if necessary.
