The cleaning blade [A] removes any toner remaining on the drum after the
image is transferred to the paper. This machine uses a counter blade system.
The toner remaining on the drum is scraped off by the cleaning blade, and it
falls onto the toner collection coil [B]. (an auger)
To remove the toner and other particles that are accumulated at the edge of
the cleaning blade, the drum rotate in reverse direction for about 5 mm at the
end of every copy job, as shown in the illustration. However, this is not done
during transfer roller cleaning cycle is performed.
