  2. Clean the corona wire by sliding the green tab back and forth several times.
  3. Inspect the drum surface for physical scratches or deep damage.
  4. Reset the counter: Go to 'Settings' > 'Machine Info' > 'Maintenance' > 'Drum' and press 'OK' to reset.

  • Clean frequently: Use the green tab to clean the wire whenever toner is replaced.
  • Handle with care: Never touch the drum's surface with fingers; skin oils can permanently damage it.
