Theory of Operation
Cleaning (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
(LED) to prepare the drum for the next Exposure cycle.
