6.10 DRUM CLEANING AND TONER RECYCLING
6.10.1 DRUM CLEANING
This machine employs a counter blade system. After the image is transferred to paper, a
cleaning blade (cleaning blade 1) [A] removes any toner remaining on the drum. The toner
collection coil [B] carries scraped off 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.
