   • If the defect is present on only the Gray print, replace the Black (R1) Drum Cartridge.

   • If the defect is present on only the Blue print, replace the Cyan (R2) Drum Cartridge.

   • If the defect is present on only the Pink print, replace the Magenta (R3) Drum Cartridge.

   • If the defect is present on only the Green print, replace the Yellow (R4) Drum Cartridge.

IMPORTANT:

• • There is an exception for Green. If the defect is present on both the Green print and the Blue print, replace the Cyan Drum Cartridge.
