  1. Power off the printer.
  2. Open the front panel and remove the magenta toner and drum unit.
  3. Clean the corona wire by sliding the green tab side-to-side several times.
  4. Reinsert the unit and verify that it clicks into place.
  5. Perform a drum reset through the printer's 'Menu' > 'Machine Info' > 'Reset Drum' options.
