  1. Check: Open the front cover and remove the drum set.
  2. Clean: Wipe the golden contacts (chips) of the drums with a dry cloth.
  3. Test: Reinstall the assembly and close firmly. Try a test print.
  4. Replace: If the error persists in a specific color, replace that drum.

Prevention and Maintenance

Never touch the green or blue surface of the drums with your fingers. If the environment is very dry, ensure you use a humidifier to avoid excessive static electricity on the imaging unit.
