More on Drum Cleaning
This machine uses a counter blade, but no brush.
The blade scrapes toner off the drum, and a toner collection coil picks up
toner from the top of the pile and carries it back to the development unit.
At the end of every copy job, the drum reverses for 5 mm to scrape toner
off the edge of the cleaning blade.
