Drum Cleaning
Each drum unit has a cleaning brush roller [A] and a cleaning blade [F] to remove
toner from the drum after image transfer.
[A]: Cleaning brush roller
Turns counter-clockwise, brushes unused toner from the drum surface, and
pushes the toner into a well where it is caught by the waste toner coil
[B]: Waste toner coil
The rotation of this spiral coil moves the waste toner away from the drum
toward the waste toner port
[C]: Waste toner port
The toner is moved away from this port to the waste toner collection bottle.

[D]: Lubricant brush roller
To improve the efficiency of cleaning, the rotating lubricant brush roller
lubricates the surface of the drum.
[E]: Lubricant bar
Provides the lubricant transferred to the drum surface by the lubricant brush
roller.
[F]: Cleaning blade
A counter blade in direct contact with the drum surface, gently scrapes away
remaining toner from the surface of the drum after the lubricant brush roller
cleaning and lubrication.
