After the transferring process, the drum needs to be physically cleaned of toner which is residual after the
development process. The cleaning blade is constantly pressed against the drum and scrapes the residual
toner off to the cleaning roller. The waste toner is collected at the output end of the sweep roller and sent to
the waste toner box.
After the drum 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 resid-
ual charge is canceled by exposing the drum to the light emitted from the cleaning lamp (CL). This lowers the
electrical conductivity of the drum surface making the residual charge on the drum surface escape to the
ground.
