1.3.5 Cleaning (DRUM)
In the Cleaning process, excess toner and charge is removed from the drum and BCR surfaces.
- Drum cleaning
The excess toner that was not transferred to the Transfer Belt remains on the drum surface. To
prevent troubles in the subsequent processes, the excess toner is scraped off by the Cleaning
Blade in contact with the drum, and then collected into the collection box as described in "1.3.8
Waste Toner Collection".
- BCR cleaning
The excess toner remaining on the BCR is wiped off by the Cleaning Roll made of spongy material,
and then collected into the collection box as described in "1.3.8 Waste Toner Collection".
- Charge cleaning
When the drum is charged by BCR, any excess charge hinders the drum surface from being uni-
formly charged, which may lead to print quality problems.
The excess charge on the surface of the drum is eliminated by irradiating the light of the Erase
Lamp (LED ASSEMBLY).
