scattering toner.

drum unit and toner cartridge assembly.

Clean the primary corona wire inside the 
drum unit by gently sliding the blue tab 
from right to left several times.

Return the blue tab and snap it into the 
Home position (

Reinstall the drum unit and toner 
cartridge assembly in the MFC.
