2-1-2 Drum section
The drum section consists of the drum, the charger roller unit, and the cleaning unit, and the drum surface is
uniformly charged in preparation for formation of residual image by laser beam.
After transfer is complete, toner remaining on the drum surface is chipped off with the cleaning blade and is
collected to the waste toner box with the sweep roller. The cleaning lamp (CL) consists of LEDs and removes
residual charge on the drum before main charging.
