(2-2) Charging the drum
The following shows a simplified diagram of the electrophotographic components in relation to the engine system.
Charging the drum is done by the main charger unit A.
Figure 2-1-10 Charging the drum
As the drum C rotates in a “clean (neutral)” state, its photoconductive layer is given a uniform, positive (+) corona
charge dispersed by the main charger wire B.
Due to high-voltage scorotron charging, the charging wire can get contaminated by oxidization after a long run.
Therefore, it must be cleaned periodically from time to time. Cleaning the charging wire prevents print quality problems
such as black streaks.
