8. DRUM CLEANING
8.1 OVERVIEW
This copier uses a counter blade system for drum cleaning. In a counter
blade system, the blade [A] is angled against drum rotation. This system has
the advantage of high cleaning efficiency.
The toner remaining on the drum is scraped off by the cleaning blade and it
falls onto the toner collection coil [B]. Collected toner is transported to the
recycled toner transport coil [C].
To remove the toner that is accumulated at the edge of the cleaning blade,
the drum turns in reverse for about 3 mm at the end of every copying job.
