Drum Cleaning

The lubricant brush roller [A] and the primary [C] and secondary [B] toner collection coils are driven by the drum cleaning motor through gears.

A counter blade method is adopted for the lubricant blade [D] and the drum cleaning blade [E]. The lubricant brush roller [A] rotates in the same direction as the OPC drum in order to lubricate the drum surface. The lubricant blade [D] keeps lubricant on the surface flat.

Waste toner that is collected with the drum cleaning blade [E] and lubricant are sent to the used toner transport area by the primary toner collection coil [C].

Lubricant and used toner are sent to the rear side and expelled. The vibration plate prevents the lubricant from clumping together (which can lead to the exit clogging). This vibration plate shifts up and down in accordance with the rotation of the secondary toner collection coil [B] and prevents the exit from clogging.
