Theory of Operation
Imaging Unit
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.
