Excess toner is removed from the drum and the BCR surfaces, while excess charge

is also eliminated from the drum surface.

Drum Cleaning – The cleaning blade contacts the surface of the drum

collecting the excess toner by scraping off toner.

Cleaning Roller – The cleaning roller contacts the surface of the BCR collecting

the excess toner by scraping off toner.

Charge Cleaning – When the drum is charged by the BCR, any excess charge

hinders the drum surface from being uniformly charged, which may lead to

print quality problems. The the latent charge pattern remaining on the

photoconductive drum is neutralized by the Erase Lamp to prepare the drum

for the next exposure cycle.
