The measured voltage is not correct when the EGB measures each charge output (charge, development, image transfer belt unit, and transfer unit).

  • Disconnected or defective high voltage harness
  • Defective high voltage power supply
  • Defective EGB
    1. Check or replace the harnesses.
    2. Replace the high voltage power supply board

SC396

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.)

  • Disconnected or defective motor harness.
  • Motor slips due to excessive load
    1. Check the harness from the black drum motor. Replace it if necessary.

SC397

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.)

  • Disconnected or defective motor harness.
  • Motor slips due to excessive load
    1. Check the harness from the color drum motor. Replace it if necessary.
