The cleaning blade [A] removes any toner remaining on the drum after the image is
transferred to the paper. This model uses a counter blade system.
The toner remaining on the drum is scraped off by the cleaning blade, and is
transferred to the toner collection coil [B] by the toner collection plate [C].
The collar [D] on the cleaning blade bracket contacts the outer rim of the cam gear
[E], and this gear moves the cleaning blade from side to side. (This gear is the
same cam gear that moves the cleaning pad for the charge roller from side to side.)
This movement helps to disperse spots of accumulated toner to prevent early blade
edge wear at any particular location.
To remove the toner and other particles that have accumulated at the edge of the
cleaning blade, the drum turns in reverse for about 5 mm at the end of every print
job.
