(6) Cleaning
After the transferring process, the drum needs to be physically cleaned of toner which is residual
after the development process. The cleaning blade A is constantly pressed against the drum B and
scrapes the residual toner off to the sweep roller C. The waste toner is collected at the output end
of the sweep roller C and sent back to the toner container, into the waste toner reservoir D.
Figure 4-1-12 Drum cleaning and erasing static charge
After the drum B is physically cleaned, it then must be cleaned to the electrically neutral state.
This is necessary to erase any residual positive charge, ready to accept the uniform charge for the
next print process. The residual charge is canceled by exposing the drum B to the light emitted
from the eraser lamp E. This lowers the electrical conductivity of the drum surface making the
residual charge on the drum surface escape to the ground.
