Steps to Fix Error SC300-00 (Black Charge Error)

This code directly affects the Black (K) Photo Conductor Drum Unit (PCDU):

  1. Inspect Black Drum Unit (PCDU K): Open the front cover, remove the waste toner bottle, and verify the black drum unit is fully seated.
  2. Clean High Voltage Contacts: Power down the copier, remove PCDU-K, and clean the rear gold contact pins with a dry, lint-free cloth to eliminate toner dust build-up.
  3. Inspect Charge Roller Surface: Check the charge roller inside the unit for severe toner accumulation or arcing damage.
  4. Replace Component: If cleaning contacts does not clear the code, the black PCDU or the High Voltage Power Supply board needs replacement.
