Drum Cleaning and Toner Recycling
Drum Cleaning
This machine employs a counter blade system. After the image is transferred to paper, a cleaning blade
[A] removes any toner remaining on the drum. The toner collection coil [B] carries excess toner to the toner
collection plate [C].
The collar [D] on the cleaning blade bracket contacts the outer rim of cam gear [E], which moves the
cleaning blade side to side. This side-to-side movement disperses accumulated toner to prevent early blade
edge wear at one location.
The drum reverses about 5 mm after every print job to remove particles on the edge of the cleaning blade.
